Question

can anyone fo this Q3

Answer 1

$\sqrt{0.5625} = \sqrt{ \frac{5625}{10000} } \\ \\ = \frac{75}{100} \\ \\ = 0.75 \\ \\ \sqrt{56.25} = \sqrt{ \frac{5625}{100} } \\ \\ = \frac{75}{10}$

therefore,

$\sqrt{0.5625} + \sqrt{56.25}\\ \\ = \frac{75}{100} + \frac{75}{10}\\ \\ = \frac{75+750}{100}\\ \\ = \frac{825}{100}\\ \\= 8.25$
