Evaluate -( square root of 2)/2*( square root of 2)/2

$- \frac{\sqrt{2}}{2} \cdot \frac{\sqrt{2}}{2}$

Step 1

Multiply $- \frac{\sqrt{2}}{2} \cdot \frac{\sqrt{2}}{2}$ .

Multiply $\frac{\sqrt{2}}{2}$ by $\frac{\sqrt{2}}{2}$ .

$- \frac{\sqrt{2} \sqrt{2}}{2 \cdot 2}$

Raise $\sqrt{2}$ to the power of $1$ .

$- \frac{{\sqrt{2}}^{1} \sqrt{2}}{2 \cdot 2}$

Raise $\sqrt{2}$ to the power of $1$ .

$- \frac{{\sqrt{2}}^{1} {\sqrt{2}}^{1}}{2 \cdot 2}$

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$- \frac{{\sqrt{2}}^{1 + 1}}{2 \cdot 2}$

Add $1$ and $1$ .

$- \frac{{\sqrt{2}}^{2}}{2 \cdot 2}$

Multiply $2$ by $2$ .

$- \frac{{\sqrt{2}}^{2}}{4}$

Step 2

Rewrite ${\sqrt{2}}^{2}$ as $2$ .

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{2}$ as $2^{\frac{1}{2}}$ .

$- \frac{{(2^{\frac{1}{2}})}^{2}}{4}$

Apply the power rule and multiply exponents, ${(a^{m})}^{n} = a^{m n}$ .

$- \frac{2^{\frac{1}{2} \cdot 2}}{4}$

Combine $\frac{1}{2}$ and $2$ .

$- \frac{2^{\frac{2}{2}}}{4}$

Cancel the common factor of $2$ .

Cancel the common factor.

$- \frac{2^{\frac{2}{2}}}{4}$

Rewrite the expression.

$- \frac{2^{1}}{4}$

Evaluate the exponent.

$- \frac{2}{4}$

Step 3

Cancel the common factor of $2$ and $4$ .

Factor $2$ out of $2$ .

$- \frac{2 (1)}{4}$

Cancel the common factors.

Factor $2$ out of $4$ .

$- \frac{2 \cdot 1}{2 \cdot 2}$

Cancel the common factor.

$- \frac{2 \cdot 1}{2 \cdot 2}$

Rewrite the expression.

$- \frac{1}{2}$

Step 4

The result can be shown in multiple forms.

Exact Form:

$- \frac{1}{2}$

Decimal Form:

$- 0.5$
