Pre-Algebra Examples

$16 = 2^{x}$

Step 1

Rewrite the equation as $2^{x} = 16$ .

$2^{x} = 16$

Step 2

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

$2^{x} = 2^{4}$

Step 3

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

$x = 4$
