Question

С

(3+√3) во 2 степени + (3-√3) во 2 степени

x+4=3/5

(1/8) во 2 степени - 3/64

Answer 1

1) 24

2) -17/5

3) -1/32

Пошаговое объяснение:

${(3 + \sqrt{3} )}^{2} + {(3 - \sqrt{3} )}^{2} = 24 \\ 9 + 6 \sqrt{3} + 3 + 9 - 6 \sqrt{3} + 3 =18 + 6 = 24$

$x + 4 = \frac{3}{5} \\ x = \frac{3}{5} - 4 \\ x = \frac{3 - 20}{5} = - \frac{17}{5}$

${( \frac{1}{8} )}^{2} - \frac{3}{64} = - \frac{1}{32} \\ \frac{1}{64} - \frac{3}{64} = - \frac{2}{64} = - \frac{1}{32}$
