Teaching Intro to Power to Power rule easily
Power to Power rule of exponents states that if an exponent expression with a base having some power and this whole exponent expression is further applied with another power can be written as the same base raised to the product of those powers.
As per the power to power rule, if (px) is further raised with power y, i.e., (px)y, then it can be written as (p)x*y or (p)XY.
For Example, solve (p2)5.
Solution: (p2)5 = (p)2 * 5 = (p)10.
Q. Solve [(a + b)5]7 using the power-to-power rule of the exponent.
Solution: (a + b)5×7 = (a + b)35
Negative exponents’ power-to-power rule:
As per this rule, a power-to-power exponent expression having any one or both negative powers will be expressed as follows.
- (p-m)-n = p-m×-n = pmn
- (p-m)n = p-m×n = p-mn
- (pm)-n = pm×-n = p-mn
For example, simplify the exponent (q-5)9 using the power to power rule.
Solution: (q-5)9 = q-5×9 = q-45.
