If your calculator has an exponentiation function, simply raise the number to the power of .5 Remember this trick: the nth root of X = X ^ (1/n)
The easiest way to do this is with a calculator. Anyway, the definitions are as follows. x to the power 1/2 is the square root of x, x to the power 1/3 is the cubic root of x, and in general, x to the power 1/n is the nth. root of x. If you also have a number other than one in the numerator: For example, to calculate x to the power 3/5 you first raise x to the power 3, then take the fifth root of the result. You can also do it the other way: first calculate the fifth root, then raise to the third power. In general, to calculate x to the power m/n, you take the nth root, then raise the result to the power m.
Multiply the number by itself.
The Nth term for a triangle number is: 0.5n(n+1)
Ah, the inverse of raising to powers is taking the root of a number. Just like how adding is the inverse of subtracting, roots are the inverse of exponents. It's all about finding balance and harmony in the world of mathematics.
