## Tabbiejack 2 years ago What is the simplified form of the expression? x^8 2y^10 5x^5

1. Tabbiejack

$x ^{8} 2y ^{10} 5x ^{5}$

Add the coefficients and variables of your terms.

4. galacticwavesXX

you would have $5x^5*x^8*2y^10\rightarrow (5x^13)(2y^10)$ x^5*x^8=x^13 that is how i got x^13 then just put everything back together and you get 5x^13*2y^10

5. galacticwavesXX

forgot to multiply the coefficients so you would get 10x^13*y^10

oh thanks I am trying to understand it a little is coming back thanks for explaining

7. Tabbiejack

here is another

8. galacticwavesXX

welcome anytime just remember that coefficients you multiply and variable with powers you add

What is the simplified form of the expression?|dw:1369536827542:dw|

10. galacticwavesXX

so we have $k^3(k^\frac{ 7 }{ 3 })^-5 \rightarrow (k^\frac{ 16 }{ 3 })^-5$ so we have [k^(16/3)]^-5

11. Tabbiejack

that is not an option

12. galacticwavesXX

im not done im just seeing if i did it correctly but what are the options because i have a possible answer?

13. Tabbiejack

o ok

14. galacticwavesXX

can i see what are the possible answers?

15. Tabbiejack

|dw:1369537422248:dw|

16. galacticwavesXX

whattt....for the problem itself is the k^3*(k^7/3)^-5 ? cause i got a totally different answer

17. galacticwavesXX

for the problem you wrote down are we trying to simplify k^3*(k^7/3)^-5 ? or did i get it wrong because none of the answers you posted did i get

18. Tabbiejack

no that is right
