Answer

Problem

Given that:
\$ (1/2)^2 \div (1/2)^4 \$

Step

Each term written as the numerals and literals

\$ (\cancel(1/2)\times\cancel(1/2)) / (\cancel(1/2)\times\cancel(1/2)\times1/2\times1/2) \$

Step

After cancellation

\$ 1/(1/2\times1/2) \$

Step

After multiplication

\$ 1/(1/4)\$

Step

Calculating the terms

\$ 1/1\times4/1\$

Step

After multiplication
