3^4x+^2=9^x+^2. what is the value of x?
1 answer:
Answer:
x = 1
Step-by-step explanation:
3^(4x + 2) = 9^(x + 2)
Make 9 with base 3.
3^(4x + 2) = (3^2)^(x + 2)
3^(4x + 2) = 3^(2x + 4)
Cancel bases.
4x + 2 = 2x + 4
Subtract 2 and 2x on both sides.
4x - 2x = 4 - 2
2x = 2
Divide 2 on both sides.
x = 1
