Equation which is correct
792 × 5 = 700 × 5 + 90 × 5 + 2 × 5
(pemdas), parenthesis then exponents.
7 * 2 = 14
14^ 7 = 105413504
I do believe that the LCD of those would be 3
So first, we multiply out the brackets.
-15x - 18 + 2 = 17 + 16x -1
Then, bring all the terms onto one side so you can solve.
-15x-18+2-17-16x+1=0
Then, we simplify this.
-31x-32=0
Then, isolate x
-31x=32
x=32/-31 or -1.03 (nearest hundredth )
hence, the common ratio of the given G.P. is 3 or −3.
