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]

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 =

It is unclear whether your equation is:

a: ((SQRT61) - 7) / 2

or

b: ((SQRT61) / 2) - 7

For a:

Type 61 SQRT.

Subtract 7.

Equals.

Divide by 2.

Equals. (Should be 0.4051248...)

For b:

Type 61 then SQRT.

Then divide by 2.

Equals.

Then subtract 7.

Equals. (Should be -3.094875...)

Good luck.

Use the x-root function, which is the 2nd function of the y^x key located just above the divide key. For example, to find the cube root of 8, press 8 2nd x-root 3 =

Two easy ways.

- You can use the factorial function, which is the shifted function of the 3 key. Calculate 52! and divide it by 5!.
- 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).

Yes. Use the 2nd [nCr] function.

52 2nd [nCr] 5 = will calculate the number of 5-card poker hands that can be dealt from a deck of 52 cards.

Hello,

The cosecant function is defined by

**cosec(x) = 1/sin(x) **

1[/] [sin] x.

Do not confuse this function with the arcsine function which is accessed by [2nd][sin to the -1]. When you use trigonometric functions make sure that the angle unit (Rad, dgree, grad) is the one you want.

Hope it helps.

Yes, you hit the yellow 2nd key and then the back arrow (it says F D above it in yellow.) It's the last key on the bottom of the left hand row.
