How do i plug in ((6^2+7.77^2+4^2)/(2x6x7.77)) in a TI-30XA calculator?


There should not be a problem: There are no complicated functions.
I suggest you do the calculation in steps
Step 1: Calculate the numerator 6^2+7.77^2+4^2=
The result will be stored in ANS memory, which you access by pressing the ANS key (either directly if marking is on the key, or by pressing 2nd followed by the key near which is the ANS marking).
Step 2: while the result is still displayed, press the division key, then a left parenthesis to enclose the denominator. Close the right parenthesis then press =

Hi, how do i calculate log^-1(-2) on my ti-30xa? thank u.


The inverse of the log function is the power function.
For log in base 10 that inverse is 10 to a power of
More generally, let b be the base of the logarithm. If y=log_b (x) then x=b^y
For your case log=log_10, to calculate the inverse you perform 10^(-2)=0.01=1/100
On calculators the log in base 10 and its inverse share the same physical key. One is accessed directly, the other is the shifted key function.

Hi, how do i calculate log^-1 on my ti-30xa? for example, in order to calculate log^-1(-2), what do i do? thank you.


The inverse of the common log function is the power function with base 10 (10^). It shares the same physical key as the log. You acees the function by pressing [2nd] [log]

How can I find the square root of 39 on my ti-30xa? Also I would like to know how to find the cube of 9482... Help


Square root of 39: Press 3 9 [square-root] =
[square-root] is the key just to the left of the divide key.

Cube root of 9482: Press 9 4 8 2 2nd [cube-root] =
[cube-root] is the shifted function of the 0 key.

For other roots, you can use the [nth-root] function, the shifted function of the key above the divide key. For example, to calculate the fourth root of 16, press 1 6 2nd [nth-root] 4 =

Okay so i am using a TI-30XA What is the button on this calculator for (Prb) ??


There is no probability key on the 30Xa as there is on the 30XIIS. The shifted functions of the 8 and 9 keys will calculate the number of combinations and permutations, respectively. The shifted function of the 3 key will calculate the factorial. There is no random number generator.

How do I find the carrot key on my TI-30XA?


I assume you refer to the caret ^ symbol, sometimes used as an operator for exponentiation.
  • for x^2 use the key [x²].
  • for x^3 use [2nd] [x³] (alternate function of the [1] key).
  • for all other exponents, use the key:

How do I do a factorial problem on a TI-30XA? for example 52!/5!


Two easy ways.

  1. You can use the factorial function, which is the shifted function of the 3 key. Calculate 52! and divide it by 5!.
  2. You can use the nPr function, which the is the shifted function of the 9 key. 52!/5! is 52 nPr 47 (47 is 52-5).

Finding a cube root on calculator


You can calculate cube roots by using the cube root function (the 2nd-shift of the 0 key). You can calculate arbitrary roots by using the x-root function (the 2nd-shift of the y^x key, just above the divide key).
