Question

Simplify the following
4√15 x 3√3

Answer 1

Step-by-step explanation:

$4 \sqrt{15} \times 3 \sqrt{3} \\ = 12 \sqrt{45} = 12 \sqrt{3 \times 3 \times 5} \\ = 12 \times 3 \sqrt{5} \\ = 36 \sqrt{5}$

Answer 2

Given that

$4 \sqrt{15} \times 3 \sqrt{3}$

To simplify it

Solution

$4 \sqrt{15} \times 3 \sqrt{3}$

Do the simple multiplication of number then do multiplication of values in square root

$= 12 \sqrt{45}$

45 is the product of 9 and 5

then

$= 12 \sqrt{9 \times 5}$

9 is the square of 3 hence

$= 12 \times 3 \sqrt{ 5} \\ = 36 \sqrt{5}$

hence solution of equation is

$36 \sqrt{5}$
