Question

The value of 2-² is
(a) 4 (b) 1/4 (c) 2 (d)1/2 ​

Answer 1

Answer:

(b) $\frac{1}{4}$

Explanation:

To find the value of:  $2^{-2}$

Proof:

= $2^{-2}$

= $\frac{1}{2^{2} }$                                       [ $a^{-m} = \frac{1}{a^{m} }$ ]

=  $\frac{1}{4}$                                       [ $2^{2} = 4$ ]

Hence, proved.

Hope you got that.

Thank You.
