Question

Solve for x ( 81)^x-1 = (27)^x+1​

Answer 1

Answer:

x is equal to 54 of this question

Answer 2

Answer:

$81^{x-1}=27^{x+1}$

Here, We can simplify 81 and 27 into 3⁴ and 3³

$3^{4(x-1)}=3^{3(x+1)}$

Now, we can equate the equation by removing 3.

4(x-1)=3(x+1)

4x-4=3x+3

Bring variables to one side, constants to one side.

4x-3x=3+4

x=7

HOPE THIS HELPS :D
