That's a misleading proof though.

You mean this: (a103)(b73)

But I mean this: (a103)(b73)

There are major differences between the 2 equations.

And I guess the asker means my equation because he said simplified radical form and that's a term for 'Law of Indices'.

Simplify the following:
(a^10 b^7)/(3×3)
3×3  =  9:
Answer: |  (a^10 b^7)/9

Express (a^10/3)(b^7/3) in simplified radical form

 

Proof: let a=3, b=2

(3^10/3) x (2^7/3) =839,808

(3^10 x 2^7) / 9 =839,808

 

MaxWong's Solution:

[3^10 x 2^7]^(1/3)=196.25

It is NOT: a^(10/3), or b^(7/3)!!!.
