Question

помогите пожалуйста решить

Answer 1

2)
$\sqrt{2 + \sqrt{ \frac{68({32}^{2} - {15}^{2} ) }{47} } } =$
$\sqrt{2 + \sqrt{ \frac{68(32 - 15)(32 + 15)}{47} } } =$
$\sqrt{2 + \sqrt{ \frac{68 \times 17 \times 47}{47} } } =$
$\sqrt{2 + \sqrt{ \frac{68 \times 799}{47} } } =$
$\sqrt{2 + \sqrt{68 \times 17} } = \sqrt{2 + \sqrt{1156} } = \sqrt{2 + 34} = \sqrt{36} = 6$

Answer 2

1) √12/25 √( 244/15*15*61) = √12/25 * √4/225=√12/25* 2/15 = √8/125 = 2/5√2/5

2)√2+√( 68*17*47/47) = √2+√68*17=√2+17*2=√36=6
