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,
\(\sqrt{28} + \sqrt{64}\)
Solved:
We can re-write 64 as 8^2.
\(= \sqrt{28} + \sqrt{8 {}^{2} }\)
\(= \sqrt{28} + 8\)
Rewrite 24 as,
\(= \sqrt{2 {}^{2} \times 7 } + 8\)
Bring terms out of the root √ as :
\(= \boxed{ 2 \sqrt{7} + 8}\)
\(\boxed{ \approx13.30}\)
