Step 2.2.1

Raise $0.06$ to the power of $7$ .

$r = \frac{420}{1 - 1 \cdot 0}$

Step 2.2.2

Multiply $- 1$ by $0$ .

$r = \frac{420}{10}$

Step 2.2.3

Subtract $0$ from $1$ .

$r = \frac{420}{0.99999999}$

$r = \frac{420}{0.99999999}$

Step 2.3

Divide $420$ by $0.99999999$ .

$r = 420.00000117$

$r = 420.00000117$
