oops typo there

3. misty1212

$\huge \frac{1}{p^5}=\frac{1}{243}\iff p^5=243$

4. dinamix

1/3^5

5. misty1212

think of a number that, when raised to the power of 5, gives 243 make a guess (hint, it has to be pretty small)

6. dinamix

7. sissyedgar

well, in order to be a multiple of 5 it has 2 end in 0 or 5, which it doesnt... 48.2

8. skullpatrol

Do you know the definition of a negative exponent @sissyedgar?

9. misty1212

no dear, not a multiple of 5, multiplying by itself five times like for example $2^5=2\times 2\times 2\times 2\times 2=32$

10. sissyedgar

o yah rite rite

11. skullpatrol

$$\Huge a^{-n}=\frac{1}{a^n}$$

12. sissyedgar

3 times is 125...

13. misty1212

no that is $$5^3=125$$

14. misty1212

but you are close, try $$3^5$$

i annoy myself! DUHR! its 3

17. dinamix

$\frac{ 1 }{ 3*3*3*3*3 } = 1/ 3^5 = 1/243$

18. sissyedgar

ty Misty

19. dinamix

did u know how analysis of the number to multiplying the initial factors ?

20. dinamix

|dw:1440682037462:dw| like this example
