1)
4^(0,5) *3^(0,5) *3^(0,5)*7^(5/3) 3*7
----------------------------------------- = -------------------- = 3*7=21
4^(0,5)*2^(0,5) *2^(-3/6)*7^(2/3) 2^(0,5) *2(-1/2)
ответ 2) 21
2)
= a^ (3*2/4 ) : a^(3/2) = a^(3/2) : a^(3/2) = 1
ответ 2) 1
3)
= (1+b^(1/3)) *(1-b^(1/3) +b^(2/3)) / (1-b^(1/3)+b^(2/3)) - 2b^(1/6)=
=1+b^(1/3) -2b^(1/6) = (1-b^(1/6))²
