i need help asap! please. :)
ok, can somebody explain how to do this? simplify by adding like terms. write the answer with all variables in the numerator. x^2y 4x^2p^3 2xp 5y ---- - ------- - ------- - ----- p^-3 y^-1 y^-1p^2 p^-3x^-2 PLEASE HELP ME!!!! i'm homeschooled so i cant continue w/ the rest of ...

Express cube root 27x^4y^6 using rational exponents (27x^4y^6)1/3 (27^1/3)(x^4/3)(y^6/3) stuck. I think the final answer is 9x^3/4(y^2) I don't know where to put the parentheses to break it up so I hope yall understand what it's suppose to be.

Just use the rules for adding and subtracting exponents of the same number, when multiplying or dividing. (4^3 x 5^-2)(5^4 x 4^-5)/ (4^-3 x 5^3) = 4^-2 x 5^2/(4^-3 x 5^3) = 4^1 x 5^-1 = 4/5 Do the second problem the same way

first, express 4 as a power of 2,, 4=2^2 then divide both sides by 2^2 2^(-x+1)/2^2 = 8^x *note, at the right side of equation, 4 and 2^2 canceled each other* then recall some laws of exponents. since on the left side, the numerator and denominator have the same base (which is...

Use rational exponents to write 4suare root 5 * 2 sqaure root 8 Please help.. I can't find the square root button

The subject is rational (fractional) exponents, not radical. 4sqrt5 * 2 sqrt8 = 8 sqrt40 = 8 sqrt(4*10) = 16 sqrt10

I need to know if i answered this right. Use the laws of exponents to simplify. 3^3/4 * 3^1/8= 81/32

exponents means to multiply by itself,, thus: (A) (-1)^3 = (-1)(-1)(-1) = ? *solve for this. (B) here, only 1 is raised by 3,, the negative sign (or the -1) is excluded: -(1)^3 = -(1)(1)(1) = ? (C) process is same as that of letter (A) (D) process is same as that of letter (B...

You may put the exponents in the numerator or denominator. a3= 1/a-3 sometimes teachers have beginning students move them around just for practice.

Math: Rational Exponents
simplify completely. give your answer without fractional exponents. (8(s^-3)*(t^5))^(3/5)/(2(s^7)*(t^-2))^(3/5))

Exponents and Roots - eh?
unbalanced parentheses use ^ for exponents, as x-squared for x^2

n^0 = 1 unless n=0 consider the rules of exponents n^6/n^2 = n^(6-2) = n^4 when dividing, subtract exponents. so, n^6/n^6 = n^(6-6) = n^0 = 1

simplify the following. leave answers with positive exponents 1) c^2 x c^7= c^9 2) (2w^2 x^4)^3= (2w^5 x^7) 3)(a^4)^12= a^16 4) 28x^2/ y^-9= i don't undestand this 5) (3b)^3= 3b^4 6) x^14/x^6= x^8 7) 977^0= 977 8) (x/y)^8= i don't understand

#4 and #5 are both correct. For #8, it is x^8/y^8, since the question requires positive exponents. (You could have written it as x^8y^-8.) 1. 1/125 is 1/5^3. See if you can find the correct answer. 2. d^4*d^6 is d^10, so correction required. 3. the minus sign before the ...

(Math)Simplifying using the laws of exponents
multiply: add exponents raise to power: multiply exponents (x^3/4 y^1/3)^2/3 = x^(3/4*2/3) y^(1/3*2/3) = x^1/2 y^2/9 (x^-1/3 y)(x^1/2 y^-4/3) = x^(-1/3 + 1/2) y^(1 - 4/3) = x^1/6 y^-1/3 = x^1/6 / y^1/3 (4a^2 b^-7/2)^1/2 = 4^1/2 a^(2*1/2) b^(-7/2*1/2) = 2a b^(-7/4) = 2a / b^7/4...

I know that anything to the power of 0 is 1 but I need help with these 2 questions and check my answers: (xy)^0 / (z^2a^1)= (-2mn^2)^1 / (pqm)^0= (xy^2z)^0= 1? Negative Exponents: it says to leave answers with positive exponents only, I did all these questions so please check ...

Math: law of exponents check answers
Look, the law of exponents applies to all... You had a 3^1 in the denominator, specifically (3^1...)^-2 and that changes to 9 in the numerator. Law of exponents does not apply to just variables.
