Let (17)3.5 x (17)x = 178
Then, (17)3.5 + x = 178
∴ 3.5 + x = 8
⇒ x = (8 - 3.5)
⇒ x = 4.5
Then, (17)3.5 + x = 178
∴ 3.5 + x = 8
⇒ x = (8 - 3.5)
⇒ x = 4.5

By LAW OF INDICES :-
(a)^m × (a)^n = a^(m+n)
i.e., During MULTIPLICATION ,when bases (a&a) are common , we can add the powers. so ,
(17)^3.5 × (17)^x = (17 )^8
17^(3.5+x) = (17 )^8
When we have same base on both sides , we can equate it as follows:-
3.5+x= 8; x= 8-3.5;
Hence , x = 4.5 .
(a)^m × (a)^n = a^(m+n)
