MHB How to Use Exponents and Roots on a Scientific Calculator?

[goosey00]

On a scientific calculator, how do you get a root of a number for an exponiental? Ex.-.653846^1/12=
I was taking 1/12 and making it so I can make it exponent for .653846. Obviously wrong. What am I doing here??

Largely depends on what calculator you have. On my Casio fx-83ES one would type

-0.653846 x[sup]y[/sup] ( 1 / 12)

although y is a box - can't show it on my keyboard.

Im still getting it wrong though. What do you get to check the answer

Maybe it's how I'm asking. It says simplify b=(squiggy equal sign).653846^1/12

Hi goosey00,

Welcome to MHB! :) When you make a post you might notice a yellow column on the right hand side. If you look to the top of this column and click "Scientific Calculator" then a calculator will popup where you can practice making these calculations. What did you get for your final answer?

Purchasing power=

For the orginal purchasing power f(t)=1.08 (.926127)
For the one part I got at f(t)= .40 (.931511)
They want me to know where they intersect. If you need more info, let me know

I'm a little confused. Is this a new problem or the same one? If it's a new one then you can make a new thread in a different section of the site, but if it's still about using your calculator then let's continue the discussion here :)

Either way can you post the complete problem?

Ok, I'll be around and someone will surely help you today. I am on this site every day at different times and so are many others so you don't need to every worry about no one reading your questions.

1. Do you want to valuate

\displaystyle{\sqrt[12]{-.653846}}

You'll get an error message because an even root of a negative number has not a real value.

2. Do you want to valuate

(exp(-.653846))^(1/12)

Determine first \displaystyle{e^{-.653846} \approx 0.52}
and afterwards the 12^th root.
