Basic Math Examples

$y = 2^{- (2)}$

Step 1

Multiply $- 1$ by $2$ .

$y = 2^{- 2}$

Step 2

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$y = \frac{1}{2^{2}}$

Step 3

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

$y = \frac{1}{4}$

Step 4

The result can be shown in multiple forms.

Exact Form:

$y = \frac{1}{4}$

Decimal Form:

$y = 0.25$
