Answer 1

Answer:

18

Step-by-step explanation:

(3√2)^2

=9*2...….. [3*3=9 √2*√2=2]

=18

Answer 2

Answer:

The Answer is 18.

The explanation :

This is the number given

$3 \sqrt{2}$

Now we have split the number like this

$3 \times \sqrt{2}$

Now do the square of 3

${3}^{2} = 9$

Now do the square of

$\sqrt{2}$

We get

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

How this is possible, explanation given down

$\sqrt{2} = {2}^{ \frac{1}{2} }$

Now squaring it we get

${2}^{ \frac{1}{2} } \times {2}^{ \frac{2}{} }$

We get it to be 2 .Hence 2 ×9=18.
