These Exponents Worksheets are a good resource for students in the 5th Grade through the 8th Grade. We derive these laws here using some good examples. Lesson 1: Laws of Exponents Law 2: Quotient Law m a n = am-n a When dividing two powers with the same base, just subtract the exponents. Square Roots. The term power (Latin: potentia, potestas, dignitas) is a mistranslation of the ancient Greek δύναμις (dúnamis, here: "amplification") used by the Greek mathematician Euclid for the square of a line, following Hippocrates of Chios.
