= (6)^6.5 × [(6)^2]4.5 ÷ [(6)^3]4.5

= (6)^6.5 × (6)^9 ÷ (6)^13.5

= (6)^(6.5 + 9 - 13.5)

Abhishek Chowdhury  (8 years ago)

you guys get it wrong i guess...I think the question is (6^6.5) * (36^4.5) / (216^4.5) = (6^?)

Soln:
[sqroot (6^13) * sqroot (36^9)] / sqroot (216^9)
= (6^6)sqroot(6) * (36^4)sqroot(36) / (216^4)sqroot(216)
= 36 i.e (6^2)
so Ans is 2.
