Question

Help 50 points please

Answer 1

The first one
$\sqrt{4} + \sqrt{36} = 2 + 6 = 8$
the second one
$\sqrt{ \frac{18}{50} } = \sqrt{ \frac{9}{25} } = \frac{3}{5} = 0.6$

Answer 2

Answer:

Q1: $\sqrt{4}  + \sqrt{36}  = 8$

Q2: $\sqrt{}\frac{18}{50} = \frac{3}{5}$

Step-by-step explanation:

Q1: $\sqrt{4} = 2\\\\\sqrt{36} = 6$

6 + 2 = 8

Q2:

Cancel the common factors: 2

$\sqrt{}\frac{18}{50}  = \sqrt{}\frac{9}{25}$]

Apply the radical rule(if you need to know what radical rule is, please ask in comment section)

$\sqrt{9} /\sqrt{25}$

Factor the number: 25 = 5²

$\sqrt{9} /\sqrt{5^2}$

Apply the radical rule

$\sqrt{9} / 5$

$\sqrt{9}  = 3$

$\frac{3}{5} or .6$

hope this helps
