Question

Упростить, помогите решить срочно.

Answer 1

$({ {a}^{ - \frac {3}{5} } })^{5} \times ({ {b}^{ - 8} })^{ - \frac{3}{8} } = {a}^{ - \frac{3}{5} \times 5 } \times {b}^{ - \frac{3}{8} \times 8} = {a}^{ - 3} \times {b}^{ - 3} = {(ab)}^{ - 3} \\ { ({b}^{ \sqrt{7} - \sqrt{2} } )}^{\sqrt{7} + \sqrt{2} } = {b}^{( \sqrt{7} - \sqrt{2} ) \times ( \sqrt{7} + \sqrt{2} )} = {b}^{ { \sqrt{7} }^{2} - { \sqrt{2} }^{2} } = {b}^{7 - 2} = {b}^{5} \\ { {( {b}^{ - 4}) }^{( \frac{1}{4} )} }^{3} = { ({b}^{ - 4} )}^{ \frac{3}{4} } = {b}^{ - 3} = \frac{1}{ {b}^{3} }$
