I need to raise a neg power

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.

Hope it helps.

The key is marked y^x and is just above the divide key.

As an example, to raise 2 to the -3 power, press 2 y^x +()- 3 =

+()- is the key between the decimal point and = keys.

Use the +- key to the right of the decimal point to enter negative values and to change the sign of an existing value. For your sample:

2 EE +- 3 LOG +- =

2 EE +- 3 LOG +- =

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.
