Answer 1

1)

$\sqrt{4} + \sqrt{x} = 5$

$\sqrt{x} = 5 - 2$

$x = 9$

2)

$\sqrt{1.44} - \sqrt{36} = \sqrt{ \frac{144}{100} } - \sqrt{36} = \sqrt{ \frac{36}{25} } - \sqrt{36} = \frac{6}{5} - 6 = - \frac{24}{5}$

3)

$\frac{ \sqrt{x} }{ \sqrt{9} } = 2$

$\sqrt{x} = 6$

$x = 36$

4)

$\sqrt{x} \times \sqrt{ \frac{1}{9} } = 4$

$\sqrt{x} = \frac{4}{ \frac{1}{3} }$

$\sqrt{x } = 12$

$x = 144$
