Common Core Math: Grade 8: Expressions & Equations
In eighth grade, students use exponent laws to efficiently simplify expressions with exponents. Fluency with the properties of exponents allows students to express and perform operations with numbers in scientific notation. Students also learn to solve an equation for an unknown quantity, including when the equation involves exponents or radicals, and learn to solve a system of two equations for two unknowns.
