Question

What is $5$ squared times $3$ cubed?

• A. 675

Answer 1

The correct option is A 675
$5$ squared $=5^2,$ which is $5$ to the $2^{\text{nd}}$ power, i.e., $5$ is multiplied by itself $2$ times.

$\therefore \underset{–}{5^2=5\times 5=25}$

$3$ cubed $=3^3,$ which is $3$ to the $3^{\text{rd}}$ power, i.e., $3$ is multiplied by itself $3$ times.

$\therefore \underset{–}{3^3=3\times 3\times 3=27}$

Hence,
$5$ squared times $3$ cubed
$=5^2\times 3^3$
$=25\times 27$
$=675$
