Verified Answer :

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, \(h^{-18}* h^3\)/\(h^{0}\)
We can conclude that \(h^{0}\) is 1 because,
any number to the power of 0 is 1
\(\frac{ h^{-18}* h^{3} }{1}\)=\(h^{-18} * h^{3}\)
take the exponents alone:
-18+3 (Because it is multiplication) =-15
Final answer: \(h^{-15}\)
