Question

Simplify : √72+ √800 - √18​

Answer 1

Hey Mate

Your answer is here

We know that

√72 = √36×2 = 6√2

and √800 = 20√2

& √18 = 3√2

So,

√72 + √800 - √18

= 6√2 + 20√2 - 3√2

= 23√2

Answer 2

Hello Mate here is your answer below.

$\sqrt{72} + \sqrt{800} - \sqrt{18} \\ = > \sqrt{2 \times 2 \times 2 \times 3 \times 3} + \sqrt{10 \times 10 \times 2 \times 2 \times 2} - \sqrt{2 \times 3 \times 3} \\ \\ now \: we \:take \: common \: multipul \: \\ \\ \sqrt{2 {}^{2} \times 3 {}^{2} \times 2 } + \sqrt{10 {}^{2} \times 2{}^{2} \times 2 } - \sqrt{3 {}^{2} \times 2 } \\ \\ 2 \times 3 \sqrt{2} + 10 \times 2 \sqrt{2} - 3 \sqrt{2} \\ 6 \sqrt{2} + 20 \sqrt{2} - 3 \sqrt{2} \\ 26 \sqrt{2} - 3 \sqrt{2} \\ 23 \sqrt{2}$

I hope that helps you....
