4^(x+2) = 4^x * 4^2 = 48 48/16 = 3 4^x = 3

3. anonymous

how u get 4^2?

4. anonymous

could have sworn we just did this!

5. amistre64

4^(a+b) = 4^a * 4^b

its just a rule of exponents

8. anonymous

oh ok laws of exponents. $4^m \times 4^n=4^{n+m}$

i'm just going to keep giving amistre more medals so he can tell me about his new bike when he gets it

10. anonymous

but we are using it from right to left $4^x\times 4^2 =4^{x+2}$

11. amistre64

Natala i was going from the right hand side $4^{x+2}$ to the left hand side $4^x\times 4^2$

16. anonymous

that is where the $4^2$ came from

18. anonymous

k?

19. anonymous

good. now it is clear where it 16 came from and so you divide to get $4^x$ by itself

20. anonymous

I get it now thank again
