Question

0.0081^(-1/4) - [（7/8）^(-2.6)]^0 + (³√4)^(3/4) x (2√2)^

Answer 1

0.0081^(-1/4) - [（7/8）^(-2.6)]^0 + (³√4)^(3/4) x (2√2)^(5/3) - 16^0.75

=(0.3^4)^(-1/4)-1+[2^(2/3)]^(3/4)×[2^(3/2)]^(5/3)-(2^4)^(3/4)

=0.3^(-1)-1+2^(1/2)×2^(5/2)-2^3

=10/3-1+2^(1/2+5/2)-8

=10/3-1+2^3-8

=10/3-1+8-8

=7/3
