when adding square root of 9 and -7 which type of number is the sum?
irrational
whole number
radical
integer
Integer
sqrt 9 + sqrt -7 ????
3 + i sqrt 7
which is complex and irrational
If you mean sqrt(9-7) that is sqrt(2) which is irrational
if you mean sqrt(9) -7
that is 3-7 = -4
which is an integer
thank you :)
Well, when you add the square root of 9 and -7, you get the square root of 2! And what type of number is the sum? It's irrational! Just like my fear of clowns hiding in sewers. You never know when they'll pop out and surprise you!
When adding the square root of 9 and -7, we need to evaluate each square root separately.
First, let's find the square root of 9. The square root of 9 is 3 because 3 times 3 equals 9.
Next, let's find the square root of -7. However, the square root of a negative number is not a real number, so it is considered an imaginary number.
Now, let's add the square root of 9 (which is 3) and the square root of -7 (which is an imaginary number). When adding a real number to an imaginary number, the result is an imaginary number.
Therefore, the sum of the square root of 9 and -7 is an imaginary number.
