①8的4分之3*2的2分之1*4的4分之3
=(2^3)^3/4*2^1/2*(2^2)^3/4
=2^(9/4+1/2+3/2)
=2^17/4
②3的3分之1/9的4分之1*27的4分之1
=3^1/3/(3^2)^1/4*(3^3)^1/4
=3^(1/3-1/2+3/4)
=3^1/12
③根号?*4次根号8
③3次根号16/三次根号2
=2^4/3/2^1/3
=2^(4/3-1/3)
=2
④4次根号3*根号27
=3^1/4*3^3/2
=3^(1/4+3/2)
=3^7/4
⑤3次根号3*3次根号12
=3次根号(3*12)
=3次根号36
③根号8*4次根号8=2^3/2*2^3/4=2^(3/2+3/4)=2^9/4
