Question about Casio FX-300MS Calculator

Can't quite make out the detail on buttons on the image I have of your calculator but here goes.

say for example, the geometric mean of 2 × 3 × 6 × 8 is the 4th root of 288, or approximately 4.12.

enter nth root first, in this case 4 then shift then root symbol then open bracket, 2x3x6x8, close bracket then = ,

should give you 4.1195 etc

Are you trying to find a particular term in the geometric sequence?

For example, in the geometric sequence 2,4,8,16 to find the 15th term we would use the formula a sub n = a sub 1 x r ^(n-1), where a sub n is the nth term of the geometric sequence

a sub 1 is the 1st term of the geometric sequence

r is common ratio between successive terms

n is the term you are looking for

In our example, a sub 1 is 2, r is 2 and n is 15.

a sub n = a sub 1 x r ^(n-1)

a sub 15 = 2x 2(15-1)

a sub 15 = 2 ^ 15

a sub 15 = 32,768

On your calculator, you use the key to the right of x^2 to do x to the nth power.

Good luck.

When an HP calculator displays pend(ing) it is waiting for the user to complete the command. From what I understand you are raising some number to a power. You enter the number (base) you press a shift key of some sort then the [Y^x] and the calculator displays pend. It is waiting for you to enter the exponent.

Do you mean the "geometric mean"? If so, multiply all the numbers together then take the n-th root, where n is the number of data points.

The mean is a measure of central tendency, an average. There are several different types of means, including arithmetic mean, geometric mean, and harmonic mean.

You use the power root function key accessible with the key sequence [SHIFT][X ^]. I am inserting a screen capture from the manual to show you the sequence.

On the third line of the capture (power root) is the key you must press. In the small rectangle to the left of the radical sign you enter the order of the root: 2 for square root, 3 for cube root, 4 for 4th root and son on.

To calculate the decimal log you use the [LOG] key as shown on capture. For natural log (ln), use the [LN] key. The argument (2/3) in your example should be enclosed inside the parentheses.
