Answer 2

Given,

$\sqrt{12}$×$\sqrt{15}$

To Find,

$\sqrt{12}$×$\sqrt{15} =?$

Solution,

We can solve the question using the following steps:

$= \sqrt{12}$×$\sqrt{15}$

$= \sqrt{180}$

$= \sqrt{9*20}$

$= \sqrt{9*4*5}$

$= \sqrt{9}\sqrt{4} \sqrt{5}$

$= 3*2*\sqrt{5}$

$= 6\sqrt{5}$

Therefore,

$\sqrt{12}$×$\sqrt{15}$ $= 6\sqrt{5}$

Hence, √12 X √15 is equal to 6√5.
