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