Evaluate the following:
(a) $(5)^{3}$
(b) $(20)^{3}$
Given :
The given terms are $(5)^{3}$ and $(20)^{3}$.
To do :
We have to evaluate the given terms.
Solution :
(a) $(5)^{3}$
$(5)^{3}= 5 \times 5 \times 5$
$ = 25 \times 5$
$ = 125$
Therefore, the value of $(5)^{3}$ is 125.
(b) $(20)^{3}$
We know that, $(a\times b)^3 = a^3 \times b^3$
$(2 \times 10)^{3} = 2^3 \times 10^3$
$= 2 \times 2 \times 2 \times 10 \times 10 \times 10 $
$ = 8 \times 1000$
$ = 8000$
Therefore, the value of $(20)^{3}$ is 8000.
