Can you tell which one is greater $\left(5^2\right) \times 3$ or $\left(5^2\right)^3 $?
Answer
$\left(5^2\right) \times 3$ means $5^2$ is multiplied by $3$ i.e., $5 \times 5 \times 3=75$
but $\left(5^2\right)^3$ means $5^2$ is multiplied by itself three times i.e..
$5^2 \times 5^2 \times 5^2=5^6=15,625$
Therefore $\left(5^2\right)^3>\left(5^2\right) \times 3$
Given number is, $256$
It can be expressed as,
$256=2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \text {. }$
So we can say that $256=2^8$
