Question

please help me!!!!

(Solving Exponential Equations with Unequal Bases)
Solve 11.32x - 1 = 15.7 (2 points)
Answer

x ≈ 1.12

x ≈ 0.57

x ≈ 0.94

x ≈ 1.07

Answer 1

@jazy

Answer 2

it would help if you typed the question to show what is in the exponent.

Answer 3

but the general idea is if you have
\[ a^x= b \]
take the log (log base 10 or ln because they are on your calculator) of both sides
log(a^x) = log(b)
x log(a)= log(b)
x= log(b)/log(a)

that is the general idea. Can you use it to do your problem ?

Answer 4

yes; I got x ≈ 0.94 @phi

Answer 5

exactly what is the exponent in this problem. I was guessing 2x-1 ?
if so, I did not get x=0.94

Answer 6

what did you get? :/ @phi

Answer 7

what is the exponent ?

Answer 8

\[11.3^{2x-1} = 15.7\]

@InsanelyChaotic this is what @phi is asking...does the equation look like this?
