-
8 to the power of 2/3 is simply 'the cube root of 8 squared'
Thus it becomes the cube root of 64
which is 4
10 x 4 is 40
Thus it becomes the cube root of 64
which is 4
10 x 4 is 40

you need help with english too.
10x*8^(2/3)=
10x*cube root(8)^2
10x*2^2
10x*4
40x
10x*8^(2/3)=
10x*cube root(8)^2
10x*2^2
10x*4
40x

x^(a*b) = (x^a)^b
8^(2/3) = (8^(1/3))^2 = (cuberoot of 8)^2 = 2^2
8^(2/3) = (8^(1/3))^2 = (cuberoot of 8)^2 = 2^2
