Question

2 by 3 to the power minus 6 into 16 by 81 to the power 3 equals to 2 by 3 to the power x​

Answer 1

Step-by-step explanation:

Your question Requires a high amount of IQ to understand.

{(2/3)^-6} x (16/81)^-3 = (2/3)^x

{(2/3)^-6} x ((2/3)^4)^-3 = (2/3)^x

{(2/3)^-6} x (2/3)^-12 = (2/3)^x

(2/3)^-6-12 = (2/3)^x

(2/3)^-18 = (2/3)^x

Comparing both sides

x = -18
