This is a scientific calculator with a second function which can be used to get the nth root of any number. The calculator will display the nth root function like a function key.

Nunber

You could write down the answer to the first part of the calculation on paper, and enter it into the calculator again. However, it is possible that you may make an error either in writing down the number or in typing it into the calculator. A better method is to use the fact that the calculator retains the last calculated answer, which can then be inserted in the subsequent calculation using the The log is the inverse function of raising a number by a power. It takes the input number (base) and the output number and calculates which number the base must be raised to the power of to produce the output -- e.g. x^n=y --> logy(x) = n (the y would be given in subscript) and this is stated "Log base y of x equals n." If you have a modern calculator, there should be a log button with two blank rectangles allowing you to input the base and the output to find the power. On an older calculator, however, you will need to use a "log-law" to convert it into an equation involving the log function (meaning log base 10). Do this by typing logy/logx to give answer n.
