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 (β-1). This is because when you square 7i, you get -49.
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)
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.
square root of 49 is 7 square root of 121 is 11
The negative square root of 49 is -7. -7 is whole, integer, and rational number. It's not a natural or irrational number.
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 (β-1). This is because when you square 7i, you get -49.
The two square roots of any positive number are the positive square root and the negative square root. The positive square root of 49 is 7, because 72=49, while the negative square root is -7, because -72=49.
The square root of negative forty-nine (-49) has no value over real numbers. However, over complex numbers, the square root of -49 is ±7i, where "i" is the imaginary unit, which i2 = -1.
No. The square root of 49 is plus or minus 7, both of which are integers. And integers are rational numbers - whether they are positive or negative.
the 4th root of 49 is the square root of the square root of 49 since square root 49 =7 then simplify is square root of 7
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.

49 is the square root of 7
Remember when taking the square root of a number, that there is the positive answer, but also there is a negative numbert answer. An example is the square root of 49 can be either 7 or negative seven, because when you multiply negative seven times itself, you get forty nine.
Plus or minus 7.
