Can you guys help me for these questions
1. What is the value of 44? (1 point)
A. 16
B. 64
C.256
2. What is the value of 92?
A.18
B. 81
C.729
3.What is the value of 83?
A. 24
B. 64
C. 512
Please help me I have to hurry this ASAP.
the caret (^) is used to signify exponentiation when superscripts can't be used
1. 44 = 4^4 = 256
2. 92 = 9^2 = 81
3. 83 = 8^3 = 512
change of base??
not enough information
Look please help me I really gotta send this in I have 30 mins. And I will get grounded if I don't send it in and get the right answers. The lesson shows examples but it's not really helping.
THANK YOU! ILY
I GOT 100 THANK YOU!
EXAMPLE
How can you express the product of 2 used as a factor 10 times? You could write 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2. In writing this out, you can see how many times you need to write the number 2 and a multiplication symbol. There is an easier way to write this expression using exponents.
An exponent is a number that tells you how many times a factor is multiplied by itself. The factor is called the base. The base and the exponent together are a power.
In the previous example, the base is 2 since that factor is multiplied by itself, and the exponent is 10. To write this in exponential form, write the base, and then to the right, in a smaller raised font, write the exponent, 10. The power is 210.
In general, you would write a number in exponential form as base exponent.
To read an exponent, begin with the base, and then say to the ___th power. In this case, 210 is read as 2 to the tenth power.
There are special ways to read some exponents. Review the chart below.
Exponent
How to Read the Exponent
21
2 to the first power
22
2 squared, or 2 to the second power
23
2 cubed, or two to the third power
You can use mental math strategies to calculate powers with particular exponents.
Exponent
Mental Math Tip
0
Any power with an exponent of 0 has a value of 1.
Examples: 20 = 1; 10,0000 = 1
1
Any power with an exponent of 1 has a value equal to the base, because it means that the base is only written one time.
Examples: 21 = 2; 10,0001 = 10,000
2
Any power with an exponent of 2 is equal to the base multiplied by itself.
22 = 4; 10,0002 = 100,000,000
Earlier in this course, you learned that you can multiply numbers in any order and get the same product, by the Commutative Property of Multiplication. Even though exponents are repeated multiplication, the order in which you apply the numbers in a power does affect the product.
Review the examples below.
23 = 2 × 2 × 2 = 8
32 = 3 × 3 = 9
As you can see, it is important that you use the correct numbers in the expression for the base and the exponent.
Earlier in this course, you learned about numerical expressions, which are made up of numbers and operation symbols such as +, –, ×, and ÷. Numerical expressions do not have an equal sign (=) sign at the end of them. Instead of solving a numerical expression, you simplify the expression, which means grouping as many like terms together and find the value of the expression.
You also learned the order of operations for simplifying expressions. At that time, though, you had to skip the step for exponents. Now that you have learned what exponents are, you can now follow the entire order of operations.
Simplify the expression.
52 + 15
Begin with the exponent: 52 = 5 × 5 = 25
Next, solve using addition: 25 + 15 = 40
Simplify the following expressions using the order of operations.
33 × 5 – 4
(4 × 5) + 42
10 ÷ 2 + 35
