Question

Корень з 1-(3/5)'2 Помогите очень надо срочно

Answer 1

$\sqrt{1-( \frac{3}{5} )^2} = \sqrt{1- \frac{9}{25}} = \sqrt{ \frac{16}{25}} = \frac{ \sqrt{16} }{ \sqrt{25} } = \frac{4}{5} =0.8$

Answer 2

$\sqrt{ 1-(\frac{3}{5})^2 }= \sqrt{1- \frac{9}{25} }= \sqrt{ \frac{25-9}{25} }= \sqrt{ \frac{16}{25} }= \frac{4}{5}$
