Solve for d 30=d^2

$30 = d^{2}$

Step 1

Rewrite the equation as $d^{2} = 30$ .

$d^{2} = 30$

Step 2

Take the square root of both sides of the equation to eliminate the exponent on the left side.

$d = \pm \sqrt{30}$

Step 3

The complete solution is the result of both the positive and negative portions of the solution.

First, use the positive value of the $\pm$ to find the first solution.

$d = \sqrt{30}$

Next, use the negative value of the $\pm$ to find the second solution.

$d = - \sqrt{30}$

The complete solution is the result of both the positive and negative portions of the solution.

$d = \sqrt{30}, - \sqrt{30}$

Step 4

The result can be shown in multiple forms.

Exact Form:

$d = \sqrt{30}, - \sqrt{30}$

Decimal Form:

$d = 5.47722557 \dots, - 5.47722557 \dots$
