Step 1.1

Rewrite $2^{\frac{x}{2}} (4^{\frac{x}{2}})$ as ${(2 \cdot 4)}^{\frac{x}{2}}$ .

${(2 \cdot 4)}^{\frac{x}{2}} = 2^{6}$

Step 1.2

Multiply $2$ by $4$ .

$8^{\frac{x}{2}} = 2^{6}$

Step 2

Raise $2$ to the power of $6$ .

$8^{\frac{x}{2}} = 64$

Step 3

Create equivalent expressions in the equation that all have equal bases.

$8^{\frac{x}{2}} = 8^{2}$

Step 4

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

$\frac{x}{2} = 2$
