Answer: x=−1
Step-by-step explanation: 4
4x+1
=
64
1
,x
Use the rules of exponents and logarithms to solve the equation.
4
4x+1
=
64
1
Take the logarithm of both sides of the equation.
log(4
4x+1
)=log(
64
1
)
The logarithm of a number raised to a power is the power times the logarithm of the number.
(4x+1)log(4)=log(
64
1
)
Divide both sides by log(4).
4x+1=
log(4)
log(
64
1
)
By the change-of-base formula
log(b)
log(a)
=log
b
(a).
4x+1=log
4
(
64
1
)
Subtract 1 from both sides of the equation.
4x=−3−1
Divide both sides by 4.
x=
4
−4

Answer:
-1
Step-by-step explanation:
4^4x+1 = 1/64
4^4x+1 = 1/4^3
4^4x+1 = 4^-3
4 is cancelled
4x+1 = -3
4x = -3-1
4x = -4
x = -1
