Theory:

Repeat the power rule: when raising a power to a power, the base stays the same, but the exponents (or 'the powers') are multiplied together.

Important!
When raising a monomial to a power, the coefficient is raised separately, but the powers of the variable factors (letters) are multiplied by the power they are being raised by.
Study the following example.
Example:
Raise the monomial to a power R10.PNG
 
1) Split the monomial into terms (or factors). 
 
Remember: If the exponent of a variable factor is not specified, then it is \(1\). 
 
Raise each term separately.

2) The powers are multiplied by the power you are raising them by.

3) When raising a negative coefficient to the 3rd power, the result is negative.
