(17)3.5 x (17)? = 178
Answer: Option
Explanation:
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

a^m+a^n=a^m+n.according this formula sum of LHS power is equal to RHS power.i.e.3.5+4.5 = 8.

(2^n * 6^ m+1 * 2^n+1 * 3^2m)/ (3^-n * 6^2m * 2^4+m)=181398528 then the value of n is?

Simple calculation is:
(17)3.5 x (17)x = (17)8.
So, 3.5+x = 8.
Means x = 8-3.5.
x = 4.5.
(17)3.5 x (17)x = (17)8.
So, 3.5+x = 8.
Means x = 8-3.5.
x = 4.5.

(17)3.5 x(17)x = (17)8.
Therefore,(17)3.5+x = (17)8.
x = (17)8-3.5.
x = (17)4.5.
Therefore,(17)3.5+x = (17)8.
x = (17)8-3.5.
x = (17)4.5.

As per the laws of exponential (x)y.(x)m = (x)y+m.
(17)3.5*(17)x = (17)8.
3.5 + x = 8.
X = 8 - 3.5.
X = 4.5.
(17)3.5*(17)x = (17)8.
3.5 + x = 8.
X = 8 - 3.5.
X = 4.5.

@Mithun said the formula (x)y.(x)m = (x)y+m.
But in the second step when value are put then m is not write in the place after 17Ã-8 why?

Simple maths you just do 8-3.5 = 4.5.
