Question

Помогите решить пример !​

Answer 1

$( \frac{5b {}^{ - 7} }{3 {a}^{ - 4} }) {}^{3} \times 10 {a}^{6} {b}^{9}$

$\frac{125 {b}^{ - 21} }{27 {a}^{ - 12} } \times 10 {a}^{6} {b}^{9}$

$\frac{125 {b}^{ - 21} }{27} \times 10 {a}^{18} {b}^{9}$

$\frac{1250 {a}^{18} {b}^{ - 12} }{27}$

$\frac{1250 {a}^{18} }{27 {b}^{12} }$
