PowersDate: 10/7/96 at 4:34:52 From: Daniel Johansson Subject: Number to a Power Hello! What do you call it when you have a number raised to a number, like... 3 2 Daniel Johansson Date: 10/17/96 at 11:36:10 From: Doctor Jack Subject: Re: Number to a Power You have asked a really interesting question. The name for the function you are asking about is called the "power" function. Your example 3 2 would be read as "2 to the power 3", and more generally, the expression y x would be read as "x to the power y". If y is a whole number like 3, then calculating x to the power y is done by multiplying x by itself y times. The power function calculation gets more interesting if y is not a whole number. For example 1/3 3 w = 2 is defined to be the number satisfying w = 2. Using a calculator, you will find that w is approximately 1.25992. -Doctor Jack, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
