Answer 1

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

Answer 2

Answer:

The correct option is B.

Step-by-step explanation:

The given expression is

$\frac{8^{-2}}{3^{-3}}$

Using the properties of exponent it can be written as

$\frac{8^{-2}}{3^{-3}}=\frac{3^{3}}{8^{2}}$             $[\because \frac{1}{x^n}=x^{-n}]$

$\frac{3^{3}}{8^{2}}=\frac{9}{64}$

Therefore the correct option is B.
