To find the sum of the square roots of 50 and 18, we first need to calculate each square root separately.
The square root of 50 can be simplified as follows:
- √50 = √(25 × 2) = √25 × √2 = 5√2
Next, we can simplify the square root of 18:
- √18 = √(9 × 2) = √9 × √2 = 3√2
Now, we add these two results:
- √50 + √18 = 5√2 + 3√2 = (5 + 3)√2 = 8√2
Therefore, the sum of the square roots of 50 and 18 is 8√2.
In conclusion, what is true about the sum square root of 50 square root of 18 is that it can be expressed as 8 times the square root of 2.
