Work Step by Step
The rule for a product raised to an exponent states that: When an product is raised to a power, raise each factor at that power and multiply the results:
$(a\cdot b)^n=(a\cdot b)(a\cdot b)\cdot...\cdot (a\cdot b)$
$=a\cdot b\cdot a\cdot b\cdot...\cdot a\cdot b$
$=(a\cdot a\cdot...\cdot a)(b\cdot b\cdot...\cdot b)$
$=a^n\cdot b^n$
For example, $(xy)^{7}=x^7y^7$
