3.920 * (1.018)^x = 5.500

X=?

19

Step-by-step explanation:

3.920(1.018)ˣ = 5.500

First we can divide both sides by 3.920 to get: (1.108)ˣ = 1.403Then we can take the natural log of both sides to get: ln[(1.108)ˣ] = ln(1.403)We can then use logarithmic rules to move the x exponent to the front: xln(1.108) = ln(1.403) Then we can divide both sides by ln(1.108) to get: Then using a calculator we get x = 18.98 ≈19

X= 49; x = 4step 1: foilstep 2: equal both to 0step 3: find x individually
