What is the square root of negative 49?
The square root of a negative number is considered an imaginary number. In this case, the square root of -49 is 7i, where i represents the imaginary unit (√-1). This is because when you square 7i, you get -49.
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)
What is the square root of 49 and 121?

Why isn't it possible to take the square root of a negative number while you can find the cube root?
think about it this way... a negative times a negative is a positive... squaring is the same as multiplying it by itself. 4^2 is 16, 4X4 is 16. -7X-7 is positive 49. So a square can't be negative, therefore a negative cannot be square rooted.
Is the negative square root of 49 a whole number natural number integer rational number or irrational number?
The negative square root of 49 is -7. -7 is whole, integer, and rational number. It's not a natural or irrational number.
