Question

Упростить, помогите решить срочно.

Answer 1

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