Answer:

2√7 + 8

OR

≈13.30

Step-by-step explanation:

Given:

radical 28 plus radical 64

Solution:

Actually,radical means root √ .

So we could rewrite the Question as,

[tex] \sqrt{28} + \sqrt{64} [/tex]

Solved:

We can re-write 64 as 8^2.

[tex] = \sqrt{28} + \sqrt{8 {}^{2} } [/tex]

[tex] = \sqrt{28} + 8[/tex]

Rewrite 24 as,

[tex] = \sqrt{2 {}^{2} \times 7 } + 8[/tex]

Bring terms out of the root √ as :

[tex] = \boxed{ 2 \sqrt{7} + 8}[/tex]

[tex] \boxed{ \approx13.30}[/tex]
