Question

find the root of of (x + 3) (x -1)=3(x-⅓)​

Answer 1

Answer:

8^4/3 = (8^⅓)^4 ..........(or you could write it (8^4)^⅓)

As 8^⅓ = ³√8 = 2.........then the expression now becomes

2^4 = 2 x 2 x 2 x2 = 16

As 8 = 2³ then the alternative expression can be written [(2³)^4]^⅓ = 2^(3 x 4 x ⅓) = 2^4 = 16

Or simply, 8^4 = 4096 : 4096^⅓ = ³√4096 = 16
