Question

What is the solution to the equation 9(x + 1) = 27 ?

x = 2.5

x = 0.5

x = –0.5

x = –3.5

Answer 1

Open the brackets!
9x + 9 = 27!!
Now take the 9 to the RHS!
And then divide the RHS by 9!
Get the answer?

Answer 2

Oops i typed that wrong.

9^(x + 1) = 27

Is it still the same process? @AkashdeepDeb

Answer 3

No
now you know that 9^3 = 27 right?
So 9^(x+1) = 9^3
Now as the bases are same equate the powers!
Get your answer! :)

Answer 4

9^3 = 729

Answer 5

Express them in powers of 3

Answer 6

How much is 9?
It is (3^2)^3 = 3^6
! :)

Answer 7

9^a = 3^(2a)
