What is the square root of 2 over the square root of 18?
One third
What is a conjugate number of 2 plus square root of 5?
[ 2 minus square root of 5 ] is the only one.
Why cant you get the square root of the sum of numbers?
You can. Just add the numbers together, and find their square root. One plus three is four; the square root of the sum is two.
What is the square root of a negative number plus the square root of a negative number?
Nothing. You cannot have a square root of a negative number. The square root of negative one is called i, but i is an imaginary number. It does not exist and does not follow the properties of real numbers. (For example, if a and b are positive, then the square root of a times the square root of b is the square root of ab. But the square root of -7 is not the square root of 7 times i.)
How do you solve this equation x2 equals 49 using the square root property?
if x^2 = 49, then the square root property says you can take the square root of both sides as long as you make one a plus-minus. x^2 = 49, which means square root of x^2 = plus minus the square root of 49 the square root of 49 is 7, so +- 7. We get: x = plus/minus 7 (this means either positive 7 or negative 7)
