Question

Помогите решить, все что знаю, надо возвести в квадрат обе стороны

Answer 1

$33) \sqrt{\frac{4}{1-x}} = \frac{1}{9}\\\\\frac{4}{1-x} = \frac{1}{81}\\\\1 - x = 4*81\\\\1 - x = 324\\\\x = 1 - 324\\\\x = -323$

$34) \sqrt{\frac{5}{17-7x}} = \frac{1}{4}\\\\\frac{5}{17-7x} = \frac{1}{16}\\\\17 - 7x = 5*16\\\\17 - 7x = 80\\\\7x = 17 - 80\\\\7x = -63\\\\x = -9$

$35) \sqrt{\frac{4}{12-3x}} = \frac{1}{15}\\\\\frac{4}{12-3x} = \frac{1}{225}\\\\12 - 3x = 4*225\\\\ 12 - 3x = 900\\\\3x = 12 - 900\\\\3x = -888\\\\x = -\frac{888}{3}\\\\x = -296$

$36) \sqrt{\frac{1}{10-x}} = \frac{1}{7}\\\\\frac{1}{10-x} = \frac{1}{49}\\\\10 - x = 49\\\\x = 10 - 49 \\\\x = -39$
