Question

Solve 5^(x + 5) = 9^x

Answer 1

x ≈ –3.63
x ≈ –0.28
x ≈ 0.07
x ≈ 13.69

Answer 2

take the log of both sides:
(x+9)log(5) = xlog(9)

distribute:
xlog5 + 9log5 = xlog9

bring the variable to 1 side:
9log5 = xlog9 - xlog5

combine like terms:
9log5 = x(log9 - log5)

solve for x:
x = (9log5)/(log9 - log5)

Answer 3

and how do you solve for x?

Answer 4

i just showed you in the last line...
that is the exact value of x... if you want to see the value, put that expression into your calculator...

Answer 5

oh okay thank you
