Question

Помогите пожалуйста!!!

Answer 1

b * b² * b³ = b⁶

x⁶ * x³ * x⁷ = x¹⁶

(-7)³ * (+7)⁶ * (-7)⁹ = (-7)¹⁸

x⁸ : x⁴ = x⁴

a¹⁰ : a⁹ = a

(-0.5)¹⁶ : (-0.5)⁸ = (-0.5)⁸

$\frac{ {10}^{15} \times {10}^{7} }{ {10}^{19} } = \frac{ {10}^{22} }{ {10}^{19} } = {10}^{3}$

$\frac{ {7}^{8} }{7 \times {7}^{5} } = \frac{ {7}^{8} }{ {7}^{6} } = {7}^{2}$

$\frac{ { - 3}^{5} \times { - 3}^{3} }{ { - 3}^{7} } = \frac{ { - 3}^{8} }{ { - 3}^{7} } = - 3$
