Exponents with negative bases
Evaluate exponential expressions with negative bases, use odd and even rules to determine the sign of an exponential expression, and learn about powers of 1 and 0.
Apply what we know about negative numbers to determine how negative bases with exponents are affected and what patterns develop. Also learn how order of operations affect the pattern.
Discover a pattern that explains why any non-zero number to the zero power equals one.
Practice raising positive and negative numbers (integers only) to whole number powers. Watch out for mischievous negative signs that aren't really part of the base!
Practice raising fractions to whole number powers. Fractions in these problems may be positive or negative.
We can figure out whether multiplication and division problems give us a positive or negative result by thinking about how many negative numbers are used in the computation.
Use odd and even rules to determine the sign of an exponential expression.
Some examples that test our understanding of what happens when we multply or divided a bunch of positive or negative numbers.
Practice finding the signs of the answers to complex multiplication and division problems.
Any non-zero number to the zero power equals one. Zero to any positive exponent equals zero. So, what happens when you have zero to the zero power?
