1 answer:

8 0

When multiplying exponentials, there is a rule that states if the bases are the same, we add the exponents together.

In this problem, the two bases that are being multiplied are the same, x.

Therefore, we will add the exponents: x^3 • x^2 = x^5.

The correct answer is true. The exponents are added together when simplifying this expression.

Simplity (4^-2)^5 A.1/4^10 B. 4^3 C.1/4^3 D. 4^10

Goshia [24]

Answer:

$(4^{-2})^5=\dfrac{1}{4^{10}}$

Step-by-step explanation:

The given expression is : $(4^{-2})^5$

We need to simplify the above expression.

We know that, $x^{-a}=\dfrac{1}{x^a}$

$(4^{-2})^5=(\dfrac{1}{4^2})^5\\\\=\dfrac{1^5}{(4^2)^5}\\\\\because (x^b)^c=x^{b\times c}\\\\=\dfrac{1}{4^{10}}$

So, the simplified form of the given expression is $\dfrac{1}{4^{10}}$ . Hence, the correct option is (A).
