Simplify (2a^-3b^2)^3<br><br> 6b^6/ a9<br> 8b^6/ a^9<br> 6b^5<br> 8b
LenaWriter [7]
I'm going to assume that you accidentally missed a set of parentheses and that the expression is (2a^{-3} b^{2})^3
Raise 2, a^{-3}, and b^2 to the third power:
2^3(a^{-3})^3(b^2)^3
When a variable raised to a power is raised to another power, the exponents are multiplied:
8a^{-9}b^{6}
Negative powers are the positive power in the denominator:
\frac{8b^6}{a^{9}}
Therefore, the answer is the second option.

Multiply the polynomials (3x+5x+9)(6x-8)
STatiana [176]

Answer:

48x^2-10x-72

Step-by-step explanation:

What you do is the distributive property but at one time.

So you will multiply 6x to all the numbers. Then you will multiply -8 to all the numbers.

6x(3x+5x+9)=18x^2+30x^2+54x.

-8(3x+5x+9)=-24x-40x-72.

You will then add them together to get

48x^2-10x-72 as your answer.
