Answer 2

$\huge \underline \mathfrak {Solution:-}$

Here we have to solve ,

$\sqrt{75} - \sqrt{27}$

First of all expand these terms inside the square root by taking LCM.

$= \sqrt{5 \times 5 \times 3} - \sqrt{3 \times 3 \times 3}$

Now, take out the numbers which are two times on product inside the same square root.

So, take 5 and 3 out if square root.

= 5✓3 - 3✓3

Taking common ✓3

= ✓3 (5-3)

Subtract 3 from 5.

= 2✓3

Therefore,

$= \sqrt{5 \times 5 \times 3} - \sqrt{3 \times 3 \times 3}$ = 2✓3
