To add the numbers 321−−√ and 721, we need to simplify the square root expression first. Then, we can add the two numbers together.
Let's start with the square root expression, 321−−√. To simplify this, we need to find the square root of 321. You can use a calculator or any other method you prefer to find the square root.
Taking the square root of 321, we get approximately 17.916. So, the square root of 321 can be written as √321 ≈ 17.916.
Now that we have simplified the square root expression, we can proceed to add the two numbers:
321−−√ + 721 = 17.916 + 721
Adding the two numbers, we get:
17.916 + 721 ≈ 738.916
