Question

Evaluate: 8-2 3-3 A) - 9 16 B) 27 64 C) 16 9 D) 64 27

Answer 1

The answer to the question is c. If you are in multiplying, 8(2)= 16 & 3(3)= 9

Answer 2

The correct option is B.

Explanation:

The given expression is

`(8^(-2))/(3^(-3))`

Using the properties of exponent it can be written as

`(8^(-2))/(3^(-3))=(3^(3))/(8^(2))`
`[\because (1)/(x^n)=x^(-n)]`

`(3^(3))/(8^(2))=(9)/(64)`

Therefore the correct option is B.
