Answer 1

Answer:

1. $2 / 5$ - Fractional form, $0.4$ - Decimal Form

2. $5 / 8$ - Fractional form, $0.625$ - Decimal Form

3. $6 / 7$ - Fractional form, $0.8571$ - Decimal Form

4. $\sqrt{a / b}$

5. $\sqrt{a * b}$

Step-by-step explanation:

1. $\sqrt{4 / 25}$

Steps:

1. Divide  - $4 / 25$

2. Then take the square root of what you got - $\sqrt{0.16}$ = $0.4$

2. $\sqrt{25 / 64}$

Steps:

1. Divide - $25 / 64$

2. Then take the square root of what you got - $5 / 8$

3. $\sqrt{36 / 49}$

Steps:

1. Take the square root of the top number - 6

2. Tage the square root of the bottom number - 7

3. Answer is 6/7.

4. $\sqrt{a} / \sqrt{b}$ = $\sqrt{a / b}$

5. $\sqrt{a} * \sqrt{b}$ = $\sqrt{a * b}$

Formula:

$\sqrt{a} / \sqrt{b}$ = $\sqrt{a / b}$

$\sqrt{a} * \sqrt{b}$ = $\sqrt{a * b}$
