To take the log of a number, enter the number then press the LOG button, then the =. To take the log of a negative number, enter the negative number using the +/- key just to the right of the decimal point. To calculate the negative of a log, calculate the log and then negate it using +/-. To calculate the antilog (inverse logarithm), press 2nd then LOG.

Bear in mind that LOG is the common (base-10) logarithm. For the natural (base-e) logarithm, use the LN key to its right.

The same way you would divide by any other number. Just use the EE key (just above the 7) to enter the exponent. If the exponent is negative, use the +<>- key (just to the left of the =) to enter the negative sign.

Hi,

You have a key labeled [Y to the x], use it for all the powers or roots that do not have a dedicated key or key sequence. Let the key be [^]

Ex: 13.675 to the power 1.33 is entered as 13.675 [^] (1.33) [=].

The result is 32.41778634

Ex: (-64)[^](2/3) [=] gives 16 as result. The (-) is the change sign key

Ex: (2.87655)^(-6.778) is entered as 2.87655 [^] ( (-) 6.778 ) [=] 0.0007758

The (-) is the change sign (or the negative of), not the regular minus. When you have a negative exponent or a complicated exponent, it is safer to enclose the whole exponent inside parentheses.

Hope it helps.

Hello,

Use the Y to the x key [Y^x]. To enter the negative exponent use the change sign key [+/-] not the regular minus - sign.

Hit the buttons in this order:

3

y^x

2

+-

=

You can also find 3 to the second power and then divide the number 1 by your answer.

Since y^-x is the same as 1/y^x

Hope this helps.

You have to use the EE button right next to the parenthesis and the sigma plus button. So 1.7 EE and then your exponenet. If it is a negative exponent you need to hit the negative button before you type in the number.
