Simplify each expression.

(8b^(2/3)*9t^(1/5)) (8b^(5/3)*9t^(3/5))

 

 

 

Note: The fractions within the parenthesis simply mean they are fractions. It just looks strange within another pair of parenthesis, but I'm sure most of you have deduced that already.

 

Many thanks!!

(8b^(2/3)*9t^(1/5)) (8b^(5/3)*9t^(3/5)) ......  rearrange.......

[8b^(2/3) * 8b^(5/3)] * [ 9t^(1/5) * 9t^(3/5) ] =

[64 b^(7/3)] * [ 81 t^(4/5) ] =

5184* b^(7/3)* t^(4/5)

And that's it.....!!!!
