Handling Exponents:
Generally when handling exponents it is necessary to follow the different Law of Exponents
1. Product rule
- when multiplying exponents with the same base the exponents are added
2. Quotient rule
- when dividing exponents with the same base the exponents are subtracted
3. Power to Power rule
- when raising an exponent to another exponent you must multiply them
4. Negative exponent rule
- when an exponent is raised to a negative power the base is moved to the denominator and the sign of the exponent changes
5. Zero power rule
- any number raised to the power of 0 = 1
In this context we are finding what is equivalent to 6^8 x 6^(-4)
- using the product rule, the base is 6 in both cases so we add the exponents: 8 + (-4) = 4
- now we find what is equivalent to 6^4
- this is equivalent
- not equivalent
- not equivalent
- not equivalent
- not equivalent
- this is equivalent
The first and last options are equivalent to 6^8 x 6^(-4)
