Decimals in the exponents for TI-30Xa
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.
