7.1 Integers Exponents

California Standards 2.0 Students understand and use such operations as taking the opposite, finding the reciprocal, taking a root, and raising to a fractional power. They understand and use the rules of exponents.

x Remember! Exponent 4 Base 2–4 is read “2 to the negative fourth power.” Reading Math
