Question

solve for x: 25^x+1*125^x=25^3x-2.
Please show me the steps

Answer 1

hey please clarify the equation with use of brackets or either use the equation tool here

Answer 2

25^(x+1)*125^(x)=25^(3x-2)

Answer 3

\[\large{(5^2)^{(x+1)}\times (5^3)^x = (5^2)^{(3x-2)}}\]

Answer 4

\[\large{5^{2x+2} \times 5^{3x}= 5^{6x-4}}\]

Answer 5

\[\large{5^{2x+2+3x} = 5^{6x-4}}\]

Answer 6

2x+2+3x=6x-4
5x+2=6x-4
6=x

Answer 7

the answer is 6. Please can you try again

Answer 12

There are two ways to look at this problem:

1) Take a log base 10 on both side of the equation and you end up with a linear equation.
this is how it goes:
(2x+ 2)*log5 + 3x*log5 = (6x-4)*log5
=> (2x+2+3x) *log5 = 6x-4
=> 5x+2=6x-4
solve for x

2) find the common base as lalaly just solve above
