4 squre root 81


Take the fourth root. The square root, denoted by a 2 on top of the "root thing" or more commonly without a number at all, is the second root.

Usually the easiest way to calculate the fourth root is to calculate the square root of the square root. So in this case the fourth root of 81 is the square root of the square root of 81. The square root of 81 is 9, the square root of 9 is 3.

I cant figure out how to get the square root of a negative number


The square root of a negative number is an imaginary number, and the TI-30XA does not deal with imaginary numbers.

However, the square root of -x is equal to i times the square root of x. So, to calculate the square root of -4, for example, press 4 square_root = and read 2. Thus the square root of -4 is 2i.

How do i put the square root of a problem in a TI


Hello,
Use the square root key accessed after pressing the [2nd] function key.

Press [2nd] [Square root key] 121 [ ) ] [ENTER]. Do not forget the right parenthesis, even if you did not have to enter the left parenthesis.
The result should be 11 (one of the square roots to remember).

Hope it helps.
