Question

Помогите решить номер 2 и 3!

Answer 1

Номер 2:

1) x³ * (x⁴)³ = x³ * x¹² = x¹⁵

2) $\frac{a*a^{5}}{a^{7}} = \frac{a^{6}}{a^{7}} = \frac{1}{a}$

Номер 3:

А) 5x - 2(x - 3) = 6x

5x - 2x + 6 -6x = 0

-3x + 6 = 0

-3x = -6

x = 2

Б) 6x - (2x + 5) = 2(3x - 6)

6x - 2x - 5 = 6x - 12

6x - 2x - 6x = -12 + 5

-2x = -7

x = -7 : (-2) = 3,5
