## anonymous one year ago Write as a power of 7 7^5 x 7^3

1. Nnesha

when we multiply same bases we should add exponents $\huge\rm x^m \times x^n=x^{m+n}$

2. anonymous

Thank you Nnesha

3. Nnesha

np :=) so what did you get ?

4. ahvei

would you like a direct answer???

5. ahvei

or i can work it out a different way for you

6. Nnesha

doesn't matter if they like it or not its just against the rules.

7. anonymous

49^15? Its probably wrong xD

8. Nnesha

base would stay the same just add their exponents!

9. ahvei

its suppose to be multiplied and thats still wrong

10. anonymous

7x7^15?

11. anonymous

Realise that now, got confused.

7x7^8

15. Nnesha

yes exponent is right but it wouldn't be 7 times 7 here is an example $\huge\rm a^2 \times a^2= a^{2+2}=a^{4}$

16. Nnesha

so $\huge\rm 7^5 \times 7^3 =?$

17. anonymous

7^5+3 = 7^8

18. Nnesha

perfect!

19. ahvei

nvm then i think she has this hopefully

20. anonymous

Ahh! Thank you, I'm gonna go practice this now :P Oh and....he* lol

21. Nnesha

yes good u need to familiar with the exponent rules.

22. Nnesha

be*

23. ahvei

sorry didnt know you are a boy

24. anonymous

It's fine :P Thank you guys anyway!
