Answer:
30/√20+√5 is equal to 10/√5.
Step-by-step explanation:
Given
30/√20+√5
To find the value of 30/√20+√5
Solution:
30/√20+√5
Find factors of 20= 2×2×5
Then,
Rewrite √20 as √2×2×5
⇒30/√2×2×5 + √5
Pull terms out from under the radical
⇒30/2√5 + √5
On adding the same radicals of the denominator
⇒30/3√5
⇒3×2×5/3√5
Cancel the common factor of 3
⇒10/√5
Hence, 30/√20+√5 is equal to 10/√5.
