Spring98 one year ago how do i do this?

1. Spring98
2. Nnesha

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

3. Nnesha

so $\rm 4^4 \times 4^3 = ???$

4. Spring98

4^7

5. Nnesha

yep right now we have $\frac{ 4^7 }{ 4^5 }$ when we divide same base we should subtract their exponents $\huge\rm \frac{ x^m }{ x^n }=x^{m-n}$

6. Spring98

4^2 right?

7. Nnesha

good work!
