Question about Casio FX-300MS Calculator

Ad

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.
