1 RULES FOR EXPONENTS Epoets re used to write repeted multiplictio of the sme fctor. I the epoetil epressio, the epoet tells us how m times the bse is used s fctor:. Similrl, i the epressio, the epoet tells us there re four fctors of the bse :. Whe ou simplif epoetil epressios, it is importt to uderstd the differece betwee the epressios d (). The lck of pretheses i the epressio mes the epoet ol rises the bse to the d power. So evlutes s ( ). O the other hd, the use of pretheses i the epressio () mes the epoet rises the bse to the d power.
