kk, what is it?

2. jiteshmeghwal9 Group Title

Yup, plz tell us wht's ur question ?

@Atowe3006 Sure,What is the question mam ?

4. Atowe3006 Group Title

$-9m ^{-2}n ^{5}*2m ^{-3}n ^{-6}$

5. tcarroll010 Group Title

You merely add exponents of like bases:$-18m ^{-5}n ^{-1}$and multiply the numerics.

6. hba Group Title

Let me clear the point, $\huge\ a^x * a^y=a^{x+y}$

7. Atowe3006 Group Title

Would it be a fraction?

8. Atowe3006 Group Title

Since there is negatives?

9. tcarroll010 Group Title

So, for the base "m", you add -2 and -3 to get -5. You could represent it as a fraction.$\frac{ -18 }{ m ^{5}n }$

10. tcarroll010 Group Title

Yes, because the exponents are negative, they can go into the denominator.

Thank you so much, Can you please help me with some others? I keep watching the video my teacher gave us to watch but I barely understand it.

12. tcarroll010 Group Title

Good luck in all of your studies and thx for the recognition! @Atowe3006 I'll try to help with more. And you are welcome very much!

3. A rectangular pasture has a fence around the perimeter. The length of the fence is $16x ^{7}$ and the width is $48x ^{4}$. What is the area of the pasture? (1 point)

14. Atowe3006 Group Title

And no problem (:

15. Atowe3006 Group Title

16. tcarroll010 Group Title

np. A(rea) = (l)(w) =$(16x^{7})(48x ^{4}) = 768x ^{11}$where you add the 4 and 7 for the like base "x" and just multiply 16 by 48.

17. Atowe3006 Group Title

Oh!!! Omfg that was so blonde of me. Hah hah! I really appreciate you helping.

18. tcarroll010 Group Title

We all have little slip-ups. I do them all the time!

19. jiteshmeghwal9 Group Title

$$(-9*2)m^{-2}.m^{-3}.n^5. n^{-6}$$

20. jiteshmeghwal9 Group Title

$$\LARGE{-18m^{-2+(-3)}.n^{5+(-6)}}$$

21. tcarroll010 Group Title

A good way to remember that you add exponents for like bases when multiplying is from the following simple example:$2^{2}2^{3} = (4)(8) = 32 = 2^{5}$If you can reconstruct that when you have a "blonde" moment, you'll do great!

22. jiteshmeghwal9 Group Title

i think u can solve it further

23. Atowe3006 Group Title

Thank you!!!

24. tcarroll010 Group Title

you're welcome!
