What is the sum of the square root of 100 and the square root of 400

Answers

Answer 1
Answer:

Answer:

30

Step-by-step explanation:

Square root of a number k will turn it into a number n such that n * n = k.

The square root of 100 is 10 because 10 * 10 = 100, and the square root of 400 because 20 * 20 = 400.

Now, we just need to sum 10 and 20: 10 + 20 = 30.

Thus, the answer is 30.

Hope this helps!
