Pre-Algebra Examples

$\sqrt{72 \cdot 50 \cdot {(4 - e)}^{2}}$

Step 1

Multiply $72$ by $50$ .

$\sqrt{3600 {(4 - e)}^{2}}$

Step 2

Rewrite $3600 {(4 - e)}^{2}$ as ${(60 (4 - e))}^{2}$ .

$\sqrt{{(60 (4 - e))}^{2}}$

Step 3

Pull terms out from under the radical, assuming positive real numbers.

$60 (4 - e)$

Step 4

Apply the distributive property.

$60 \cdot 4 + 60 (- e)$

Step 5

Multiply $60$ by $4$ .

$240 + 60 (- e)$

Step 6

Multiply $- 1$ by $60$ .

$240 - 60 e$
