Question

Multiply $3\sqrt{7}\text{by}2\sqrt{7}$.

Answer 1

Step: Multiply
We are given two irrational numbers $3\sqrt{7}\text{and}2\sqrt{7}$.

We need to multiply these numbers.

So, $\left(3\sqrt{7}\right)\times \left(2\sqrt{7}\right)$

$=3\times 2\times \sqrt{7}\times \sqrt{7}$

$=6\times 7$ Because $\sqrt{7}\times \sqrt{7}$ will be 7

$=42$

Thus, the multiplication of the given numbers $3\sqrt{7}\text{and}2\sqrt{7}$ is 42.
