Final answer:
To find a regular number from a square root, look for the number that when squared equals the original number. Express the square root as a number raised to the power of 0.5. For exponential terms, make the exponent divisible by 2 and take the square root of the base number.
Step-by-step explanation:
When trying to find a regular number from a square root, you are essentially looking for the number that, when multiplied by itself, equals the original number inside the square root. For example, the square root of 25 is 5 because 5 times 5 equals 25. To express a number as a fractional power, you can write x2 = √x which indicates that the square root of x is the same as x to the power of 0.5.
For exponential numbers like 10n, to find the square root, adjust the exponent so that it's divisible by 2, then take the square root of the base number and half the exponent. For instance, the square root of 106 is 103 because (103)2 = 106. Experiment with a calculator to become familiar with these operations, or raise a number to the power of 0.25 to find the fourth root, which is equivalent to taking the square root twice.
