10(square root400 - 15)
10(20-15)
10(5)= 50
would this be correct?
yes
Yes, your calculation is correct. The expression 10(sqrt(400) - 15) simplifies as follows:
1. First, we find the square root of 400, which is 20.
2. Next, we subtract 15 from 20, resulting in 5.
3. Finally, we multiply the result (5) by 10, giving us the final answer of 50.
