Answer 1

Ответ:

Объяснение:

a)

$x^{2} - 13x^{2} + 36 = 0\\t^{2} - 13t +36 = 0 \\t = 4\\t = 9\\x^{2} = 4\\x^{2} = 9\\x=-2 \\x=2\\x=-3\\x=3\\x1=-3, x2=-2, x3=2, x4=3$

б)

$t^{2} - 33t + 32 = 0\\t=1\\t=32\\x^{5}=1\\x^{5} = 32\\x=1\\x=2\\x1=1, x2=2$

в)

$t^{2} - 7t - 8 =0\\t=-1\\t=8\\x^{3} = -1\\x^{3} = 8\\x=-1\\x=2\\x1=-1, x2=2$
