Algebraic Expressions and Index Laws (HSC SSCE Mathematics Standard): Flashcards

Letters representing numbers in algebraic expressions

Number in front of a pronumeral

Terms with exactly the same pronumerals

$a^{m+n}$ (add indices when multiplying same base)

$a^{m-n}$ (subtract indices when dividing same base)

$a^{mn}$ (multiply indices for power of power)

$1$ (any term to power zero equals one)

$a$ is the base (number/pronumeral raised to a power)

$a(b + c) = ab + ac$
