Step 1: Take the natural logarithm of both sides of the inequality.
Since the base 1.08>1, the inequality sign remains the same.
ln((1.08)n+1)>ln(3)
Step 2: Use the logarithm property ln(ab)=bln(a) to bring the exponent down.
(n+1)ln(1.08)>ln(3)
Step 3: Divide both sides by ln(1.08). Since 1.08>1, ln(1.08) is positive, so the inequality sign remains the same.
n+1>ln(1.08)ln(3)
Step 4: Calculate the numerical values of the logarithms.
ln(3)≈1.0986
ln(1.08)≈0.07696
n+1>0.076961.0986
n+1>14.2749
Step 5: Subtract 1 from both sides to solve for n.
n>14.2749−1
n>13.2749
The solution for n is:
n>13.2749
