Answer:
0.6875
Step-by-step explanation:
24.5 = 3.2⁴ˣ
To get the exponent out of its exponent form, we need to take the ln of both sides:
ln(24.5) = 4x · ln(3.2) - divide both sides by ln(3.2)
= 4x - divide both sides by 4
x = 0.6875
We rewrite it in a more functional form:
I'll make a vertical table, easier to type. For each x we subtract 3 to get y.
