Examples: = = Answer by jim_thompson5910(28704)   (Show Source): You can put this solution on YOUR website!Lets say you have something like This breaks down to Now if we multiply this out we get Which is equivalent to So this way is much faster since if we had we would have to add 5 to itself 20 times. However, we can use multiplication as a shortcut to get to the same answer. So you multiply exponents when you have an expression with an exponent (like ) that is raised to another exponent (for instance )
