Question

HURRY 98 POINT!!!!

Simplify (23)–2

A. -1/64
B. 1/64
C. 2
D. 64

Answer 1

(2 ^3)^-2

= 2^-6

= 1 / 2^6

= 1/64 answer

Answer 2

`\sf \: b) \: (1)/(64)`

Explanation:

Given problem,

→ (23) - 2

Rectifying error in the problem,

`\sf \rightarrow \: ( {2}^(3) ){}^( - 2)`

Let's solve the problem,

`\sf \rightarrow \: ( {2}^(3) ) {}^( - 2)`

`\sf \rightarrow \: {2}^((3 * - 2))`

`\sf \rightarrow \: {(2)}^( - 6)`

`\sf \rightarrow \: \frac{1}{ {(2)}^(6) }`

`\sf \rightarrow \: (1)/(64)`

Hence, option (b) is correct.
