Answer: x = -1/8
Step-by-step explanation:
Given the equation 9^x+1 - 13(3^x)+4=0
First, open the bracket, multiply 13 by 3
9^x+1 - 39^x+4=0
Combine like terms
9^x - 39^x +4 +1=0
40^x+5=0
Make x the subject
40^x=0 -5
40^x= -5
Divide both sides by 40
40^x/40=-5/40
x = -1/8
I hope this is clear, please mark as brainliest answer.
