What same number times equals 7?
It is: the square root of 7 times the square root of 7 = 7
Is 52 a square number?
Oh, dude, like, yes, 52 is not a square number. A square number is like when you can multiply a number by itself to get it, you know? Like 7 times 7 is 49, square number. But 52? Nah, no square root action happening there.
Why isn't the number 15 a square number?
It is because a whole number multiplied by itself does not equal 15. An example of a square number is 49. 7 times 7 equals 49.
What number is 7 the square root of?
49. (If any number is substituted into this question, the answer is the product of that number with itself. If the number is 7, then 7 times 7 = 49. If the number is 12, then 12 times 12 = 144 ... and so on and so forth.)
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.)
