Multiplying and Dividing Exponents are very easy. When they are multiplied, we add the exponent numbers together. When they are divided, we subtract the exponent numbers. In this example, [tex]h^{-18}* h^3[/tex]/[tex] h^{0} [/tex] We can conclude that [tex] h^{0} [/tex] is 1 because, any number to the power of 0 is 1 [tex] \frac{ h^{-18}* h^{3} }{1} [/tex]=[tex] h^{-18} * h^{3} [/tex] take the exponents alone: -18+3 (Because it is multiplication) =-15 Final answer: [tex] h^{-15} [/tex]
