Question

please do this find the value ​

Answer 1

Answer:

guessing that this is the one

Answer 2

5.

We have,
$\longmapsto \large{ \sqrt{ \frac{196}{x} } \times \sqrt{ \frac{900}{x} } = 4}$

$\implies \Large{ \sqrt{ \frac{196}{x} \times \frac{900}{x} } = 4}$

$\implies \Large{ \sqrt{ \frac{196 \times 900}{ {x}^{2} } } = 4}$

$\implies \Large{ \sqrt{ \frac{ {(14)}^{2} \times {(30)}^{2} }{ {(x)}^{2} } } = 4}$

$\implies \Large{ \frac{14 \times 30}{x} = 4}$

$\implies \Large{ \frac{42}{x} = 4}$

$\implies \Large{ x = \frac{420}{4} }$

$\implies \Large{ x = \frac{ \cancel{420} \: {}^{105} }{ \cancel{4} \: _1} }$

$\implies \Large{ x = \frac{105}{1} }$

$\implies \Large{ x = 105}$

6.

Least 6-digit number which is a perfect square = 100489

This is because
$\sqrt{100489} = 317 \: , \: \sf{perfect \: \: square}$
