Question

помогите решить пожалуйста(

Answer 1

$2 ^{3-7 sqrt{2} } *8 ^{ frac{7 sqrt{2} }{3} } =2 ^{3-7 sqrt{2} } *2 ^{3*( frac{7 sqrt{2} )}{3} }=2 ^{3-7 sqrt{2} } *2 ^{7 sqrt{2} } = \ \ =2 ^{3-7 sqrt{2} +7 sqrt{3} } =2 ^{3} =8$

Answer 2

$2 ^{3-7 sqrt{2} } *(2^3) ^{7 sqrt{2}/3 } =2 ^{3-7 sqrt{2}+7 sqrt{2} } =2^3=8$
