Question

Find the value of

$\sqrt{400} + \frac{1}{ \sqrt[2]{400} } \times 1$
​

Answer 1

Heya!

Here is ur answer...

= √400 + 2√400 × 1

= 800+2√400/2√400

= 2(400+√400)/2√400

= 400+√400/√400

= √400(√400+1)√400

= √400+1

Hope it helps

Answer 2

$\sqrt{400} + \frac{1}{ \sqrt[2]{400} } \times 1$

$= 20 + \frac{1}{20} \times 1$

$= 20 + \frac{1}{20}$

$= \frac{20 \times 20}{1 \times 20} + \frac{1}{20}$

$= \frac{400}{20} + \frac{1}{20}$

$= \frac{401}{20}$
