No number times itself can give the result of -144 .Any number has the same sign as itself has, and whenever you multiplytwo numbers that have the same sign, the result is a positive number.
Of course, not only can it be a real number but it is a real number. When you take the square root times itself, the result is a number that is real.

squaring a number is when you times it by itself. eg. 2x2 or 5x5 cubing a number is when you times it by itself and then times it again. eg. 2x2x2 or 5x5x5

that number to the fourth power.
It is a perfect square.
The result is a square number as for example 3 times 3 = 9 which is a square number
Times it again by the same number [e.g] square of 4 is 4X4=16 so square of 4 is 16
Of course, not only can it be a real number but it is a real number. When you take the square root times itself, the result is a number that is real.

If you want it completely accurate:multiply the number by itself (that is two times done)multiply that result by the number (three times done)multiply the last result by the numberrepeat step 4 until the number has been multiplied by itself 100 times (ie repeat step 3 an extra 96 times)If you want an approximation:Take the logarithm of the number (using tables/slide rule/calculator)Multiply the number found in step 1 by 100Find the anti-log of the result of step 2 (using tables/slide rule/calculator)Depending upon the number and your calculator you may get it accurately or just an approximation by using the power button of a calculator, eg 2100 could be [2][xy][1][0][0][=]
Let the number be x and so if x-20 = 32 then x = 52
An exponent is used to indicate that a number is multiplied by itself a specified number of times. For example, to multiply 4 by itself 9 times, you would write 49.
