Rules for Exponents
Product rule:
When multiplying like bases, keep the base and add the exponents.
A
^{m}
A
^{n}
= A
^{m+n}
Examples:
X
^{ 7}
X
^{ 5}
= X
^{ 7+5}
= X
^{ 12}
X
^{ -3}
X
^{ 6}
= X
^{ -3+6}
= X
^{ 3}
Quotient Rule:
When diiding like bases, keep the base and subtract the denominator exponent from the numerator exponent.
Examples:
Power Rule:
When raising a power to a power, keep the base and multiply the power.
(A
^{ m}
)
^{ n}
= A
^{ mn}
Example:
(X
^{ 2}
)
^{ 3}
= X
^{ 2*3}
= X
^{ 6}
(AB)
^{ m}
= A
^{ m}
B
^{ m}
(X
^{ 2}
Y
^{ 3}
)
^{ 4}
= X
^{ 2*4}
Y
^{ 3*4}
=X
^{ 8}
Y
^{ 12}
Negatie Exponent Rule
Examples:
Zero Exponents:
Any number (except zero) raised to the zero power is equal to 1.
Examples:
