[tex] \frac{-6*10^{-1} }{-3*10^{-2}} [/tex]
You divide -6 and -3
[tex] \frac{2*10^{-1}}{10^{-2}} [/tex]
Because the exponents are both negative, you make them positive and change the position (the exponent which is at the denominator is now at the numerator and viceversa)
[tex] \frac{2*10^{2}}{10^{1}} [/tex]
[tex] \frac{2*10^{2}}{10^1} [/tex]
You divide the exponents (so 2-1)
2*10 = 20
