0 = √0.
The square root of zero is zero.
Zero
Anything to the zero power is one. So the square root is one.
zero
X = any number you like. You see, in order to solve for x, one would have to know what those two things equaled. For instance, what if x = zero? The square root of 2 times zero multiplied by the square root of 50 times zero, is going to be zero.
There is no answer to this problem unless x is 0. For the suare root of 98x to be a real number, x has to be positive or zero. For the square root of -147x to be a real number, x has to be negative or zero. Seeing has x has to fit both requirements, the problem has an answer only if x is zero.
The square root of 81 is 9
The square root of 144 is: ± 12
Well, honey, the square root of zero is actually just zero. And guess what? Zero is as rational as it gets in the number world. So, yes, the square root of zero is a rational number. But hey, don't sweat it if math isn't your thing, we can't all be numbers wizards.
The square root of a real number is not always positive. The square root of any positive number is positive, the square root of zero is zero (not positive), and the square root of a negative number is complex (i.e. neither positive nor negative). The square root of 16 = -4 or 4. The square root of 0 = 0 The square root of -16 = -4i or 4i

No because the square root of 98 is 7 times the square root of 2
