Question

Como calcular (2*9,8*0,125)^1/2

Answer 1

$\sqrt{2\cdot9,8\cdot0,125} = \sqrt{2\cdot \frac{98}{10}\cdot \frac{125}{1000} } = \sqrt{ \frac{24500}{10000} } = \sqrt{ \frac{245}{100} } = \sqrt{ \frac{245}{100} } =\sqrt{ \frac{49\cdot5}{100} } \\ \sqrt{ \frac{49\cdot5}{100} } = \frac{ \sqrt{49}\cdot \sqrt{5} }{ \sqrt{100} } =\frac{ 7\sqrt{5} }{ 10} }$
