can someone please solve this what is going wrong in the sum​

Answer 1

Answer:

The square of 3 is 9 and you written 6....This is the error in your sum dude.

Answer 2

Answer:

-2/3

Step-by-step explanation:

9(1+4^3x) = 153/16

1+4^3x = 153/(16×9)

1+4^3x= 17/16

4^3x= (17/16)-1

4^3x= 1/16

4^3x = 1/4^2

4^3x= 4^-2

3x= -2

x=-2/3
