$(3, 24)$ and $(7, 56)$

Step 1

Use the distance formula to determine the distance between the two points.

$Distance = \sqrt{{(x_{2} - x_{1})}^{2} + {(y_{2} - y_{1})}^{2}}$

Step 2

Substitute the actual values of the points into the distance formula.

$\sqrt{{(7 - 3)}^{2} + {(56 - 24)}^{2}}$

Step 3

Simplify.

Step 3.1

Subtract $3$ from $7$ .

$\sqrt{4^{2} + {(56 - 24)}^{2}}$

Step 3.2

Raise $4$ to the power of $2$ .

$\sqrt{16 + {(56 - 24)}^{2}}$

Step 3.3

Subtract $24$ from $56$ .

$\sqrt{16 + 32^{2}}$

Step 3.4

Raise $32$ to the power of $2$ .

$\sqrt{16 + 1024}$

Step 3.5

Add $16$ and $1024$ .

$\sqrt{1040}$

Step 3.6

Rewrite $1040$ as $4^{2} \cdot 65$ .

Step 3.6.1

Factor $16$ out of $1040$ .

$\sqrt{16 (65)}$

Step 3.6.2

Rewrite $16$ as $4^{2}$ .

$\sqrt{4^{2} \cdot 65}$

Step 3.7

Pull terms out from under the radical.

$4 \sqrt{65}$

Step 4

The result can be shown in multiple forms.

Exact Form:

$4 \sqrt{65}$
