$2 = {(1 + \frac{0.05}{4})}^{5 \cdot 4}$

Step 1

Multiply $5$ by $4$ .

$2 = {(1 + \frac{0.05}{4})}^{20}$

Step 2

Convert the exponential equation to a logarithmic equation using the logarithm base $(1 + \frac{0.05}{4})$ of the left side $(2)$ equals the exponent $(20)$ .

$\log_{1 + \frac{0.05}{4}} (2) = 20$
