To unsquare a number, one must find its square root, which is a smaller number that will yield the original number that was squared. Squaring a number refers to multiplying a number by itself, or in other terms, putting a number to the exponent of two.
Continue ReadingSquaring a number is a trivial operation: the number is simply multiplied by itself. Finding the square root is often difficult unless a calculator can be used. To find the square root of a number, guess a number and square it, and then keep repeating the process until a solution is found. The more common square roots may be identifiable by observation.

Full Answer >Simplify a cube root expression by factoring out the cube of a whole number if one is present. Continue factoring until the expression no longer contains the cube of a whole number, and solve for any cube roots of whole numbers that are present.
Full Answer >The square root of 47 is 6.8556546004, which, when rounded off to four significant figures, becomes 6.856. Since 47 is not a perfect square, its square root is a decimal rather than a whole number.
Full Answer >The square root of 52 is approximately 7.21. The square root can be expressed by the formula x times x equals y, where x is the square root of y. With 52, the formula is expressed as 7.21 times 7.21 equals approximately 52.
