0 7
O x5
Write each expression using a single exponent.
1. x⁹ (1 point)
Ox11
Ox7
07
Ox5
?
The expression x⁹ can be written using a single exponent as x¹¹. Therefore, the answer is Ox11.
Write each expression using a single exponent.
2. h^14/h^5 (1 point)
Oh^-9
O1/h^9
Oh^19
Oh⁹
?
When dividing two exponential expressions with the same base, subtract the exponents. Therefore, h^14/h^5 can be simplified to h^(14-5) which equals h^9. Thus, the answer is Oh^9.

1. x^9/x^2 (1 point)
Ox^11
Ox^7
07
0x^5
?
When dividing two exponential expressions with the same base, subtract the exponents. Therefore, x^9/x^2 can be simplified to x^(9-2) which equals x^7. Thus, the answer is Ox^7.
Simplify each expression.
3. 4^4/4^6 (1 point)
O-16
O 16
O1/16
O-1/16
?
When dividing two exponential expressions with the same base, subtract the exponent of the denominator from the exponent of the numerator. Therefore, 4^4/4^6 can be simplified to 1/4^(6-4) which equals 1/16. Thus, the answer is O1/16.
Simplify each expression.
4. 5^0 (1 point)
O0
O5
O1
O-5
?
Any non-zero number raised to the power of 0 is equal to 1. Therefore, 5^0 is equal to 1. Thus, the answer is O1.
5. Replace the ____ with <, >, or = to make a true statement. (1 point)
7^4/7^2_____49
O<
O>
O=
O none of the above
The expression 7^4/7^2 is equal to 7^(4-2) which is equivalent to 7^2. Therefore, we need to compare 7^2 and 49 to find the correct answer. Since 7^2 = 49, the correct symbol to make a true statement is O=, and the answer is "7^4/7^2 = 49".
Multiply the following polynomials.
6. -2r(8r+5) (1 point)
O-16r^2 +5
O-16r^2 + 10
O-16r^2-10r
O-16r^2-10
Multiply the following polynomials.
7. 4a(a^2 + 7a + 4) (1 point)
O 4a+28a^2+ 16a
O 4a³ + 28a^2+ 16a
O 4a³ + 44a
O 44a^4
Multiply the following polynomials.
8. (2y - 3) (3y - 2) (1 point)
O6y² - 13y+6
O6y^2-13y-6
O6y²+13y-6
O6y²+13y+6
?
6. Distributing -2r to (8r+5) gives: -2r(8r + 5) = -16r^2 - 10r. Therefore, the correct answer is O -16r^2 - 10r.
7. Distributing 4a to (a^2 + 7a + 4) gives: 4a(a^2 + 7a + 4) = 4a^3 + 28a^2 + 16a. Therefore, the correct answer is O 4a³ + 28a^2+ 16a.
8. One way to multiply (2y - 3) and (3y - 2) without using the FOIL method is to use the distributive property twice. That is:
(2y-3)(3y-2) = (2y)(3y-2) - (3)(3y-2)
= 6y^2 - 4y - 9y + 6
= 6y^2 - 13y + 6
Therefore, the correct answer is O 6y² - 13y + 6.
2. Simplify the polynomial. (1 point)
3x²+5x-5x²-4x+5-2
O-8x²-9x+3
O2x²+x+3
O-2x²-9x+3
O-2x²+x+3
Combining like terms in the polynomial 3x²+5x-5x²-4x+5-2 results in -2x² + x + 3. Hence, the answer is O-2x²+x+3.
Add or subtract.
3. (8x-2y)+(3x-4y) (1 point)
O 11x+8y
O 4x-y
O 11x-6y
O 5x+2y
?
Adding (8x-2y) and (3x-4y) together give: (8x-2y)+(3x-4y) = 8x+3x-2y-4y = 11x - 6y
Therefore, the answer is O 11x - 6y.
Add or subtract.
4. (5x²-4x-1)-(-4x²-4) (1 point)
O-9x^2-8x-1
O 9x²-4x+3
Ox²-4x-3
O9x^2+4x-3
?
Distributing the negative sign in front of (-4x² - 4) gives: (5x² - 4x - 1) + (4x² + 4) = 5x² - 4x - 1 + 4x² + 4
Combining like terms we get:
= (5x² + 4x²) - 4x - 1 + 4
= 9x² - 4x + 3
Therefore, the answer is O 9x² - 4x + 3.
Write the expression using a single exponent.
6. 7^5 . 7^6 (1 point)
O 49^30
O 7^30
O 49^11
O 7^11
When multiplying two exponential expressions with the same base, add the exponents. Therefore, 7^5 * 7^6 can be simplified to 7^(5+6), which is equivalent to 7^11. The expression 7^5 * 7^6 is equivalent to (7 * 7 * 7 * 7 * 7) * (7 * 7 * 7 * 7 * 7 * 7), which equals (7 * 7 * 7 * 7 * 7 * 7 * 7 * 7 * 7 * 7 * 7). Thus, the answer is O 7^11.
Write the expression using a single exponent.
7. 6^a . 6^v (1 point)
A 6^a +v
B 6^av
C 36^av
D 36^a +v
?
When multiplying two exponential expressions with the same base, add the exponents. Therefore, 6^a * 6^v can be simplified to 6^(a+v). Thus, the answer is A 6^(a+v).
Write the expression using a single exponent.
8. 2^8/2^7 (1 point)
O 2^1
O 2^8/7
O 2^56
O 2^15
?
When dividing two exponential expressions with the same base, subtract the exponent of the denominator from the exponent of the numerator. Therefore, 2^8/2^7 can be simplified to 2^(8-7) which equals 2^1. Thus, the answer is O 2^1.
Write the expression using a single exponent. (1 point)
x^56/x^24
A x^80
B x^23
C x^32
D none of these
?
When dividing two exponential expressions with the same base, subtract the exponent of the denominator from the exponent of the numerator. Therefore, x^56/x^24 can be simplified to x^(56-24) which equals x^32. Thus, the answer is C x^32.
10. Multiply. Write the result in scientific notation. (1 point)
(9 • 10^4) (8 • 10^6)
O 7.2 . 10^25
O 1.7 . 10^11
O 7.2 . 10^11
O 1.7 . 10^25
?
When multiplying numbers in scientific notation, multiply the coefficients and add the exponents of the powers of 10.
(9 * 10^4) * (8 * 10^6) = (9*8) * (10^4 * 10^6) = 72 * 10^10 = 7.2 * 10^11
Therefore, the answer is O 7.2 x 10^11.
what is 7x+1=?
The expression 7x + 1 represents a linear function. It cannot be solved unless a specific value is given for x. For example, if x = 2, then 7x + 1 = 7(2) + 1 = 14 + 1 = 15. If you provide the value of x, I can help you evaluate the expression.
what is 7x8+1=?
Evaluating the expression 7x8 + 1, we perform the multiplication first, then add 1:
7x8 + 1 = 56 + 1 = 57
Therefore, the value of the expression 7x8 + 1 when x equals 8 is 57.
Simplify the expression.
12. (-8x) . 3x² (1 point)
A -5x^3
B -24x^2
C -24x^3
D 5x^2
?
Multiplying (-8x) and 3x² together gives: (-8x) . 3x² = -24x^3.
Therefore, the correct answer is C: -24x^3.
