## Adorkable 3 years ago 7t^9 Divided by t^6 . Help me out please?

1. LagrangeSon678

you have to use this rule of exponenets : a^m/a^n=a^m-n

2. jim_thompson5910

$\large \frac{7t^9}{t^6}$ $\large 7t^{9-6}$ $\large 7t^3$ So $\large \frac{7t^9}{t^6}=7t^3$

3. Outkast3r09

Or you can use the multiplication law

4. Outkast3r09

in that case you know that 1/t^6 = t^-6 so you get 7t^9*t^-6 (when multiplying two of the same base terms withexponents you add so it's be $7t^(9+-6) = 7t^3$

5. jim_thompson5910

type \ [ 7^{-6} = \frac{1}{7^6} \ ] to get $\large 7^{-6} = \frac{1}{7^6}$

6. jim_thompson5910

oh and remove all spaces from the code above

7. Outkast3r09

gotcha... why don't they have a fraction button in the menu >_<

8. jim_thompson5910

everything you'll need can be found in the equation editor by clicking on the "equation" button below

9. jim_thompson5910

good question, didn't realize it wasn't there

10. Outkast3r09

haha yeah it'd be useful

for more functions, look up LaTex since this is the language it's using
