Question

multiply 3 root 5 by 2 root 5​

Answer 1

Given; multiply 3 roots 5 by 2 roots 5

To Find The result of multiplying 3√5 and 2√5

Solution; This question can be easily solved through multiplication but here root is present so the method is different here we will first multiply the simple numbers and then multiply the number under the roots

3√5*2√5

=6*5

=30

Hence the value is 30

Answer 2

Answer:

3$\sqrt{5}$ x2$\sqrt{5}$  = 30

Step-by-step explanation:

Given,

Two rational numbers 3$\sqrt{5}$  and 2$\sqrt{5}$

Required to find the product of these two rational numbers

= 3$\sqrt{5}$ x2$\sqrt{5}$

In order to multiply two rational numbers, first, we should rearrange terms into integer parts and rational parts.

Then multiply the integer parts and rational parts separately

Rearranging the terms we get,

 3$\sqrt{5}$ x2$\sqrt{5}$ = (3x2)x(  $\sqrt{5}$   x$\sqrt{5}$ )

3$\sqrt{5}$ x2$\sqrt{5}$ = 6 X 5 (Since  $\sqrt{5}$   x$\sqrt{5}$ = $(\sqrt{5} )^2$ = 5)

= 30

Hence  3$\sqrt{5}$ x2$\sqrt{5}$  = 30
