The question here is little incorrect and incomplete, here is the complete question.
Prove that , (x∈R⁺)
Proof with Step-by-step explanation:
The given expression is -------(1)
Using the formula
equation 1 can be simplified to by multiplying 8th root terms
- This can be further simplified to by multiplying 4th root terms.
- which is equal to x-1 by applying same formula again
therefore, L.H.S. expression obtained is ,equal to R.H.S.
