Section CLXXI-2301 - Number and Quantity

A. Explain how the definition of the meaning of rational exponents follows from extending the properties of integer exponents to those values, allowing for a notation for radicals in terms of rational exponents.

Example: We define 5^1/3 to be the cube root of 5 because we want (5^1/3)³=5(1/3)3 to hold, so (5^1/3)3 must equal 5.

B. Rewrite expressions involving radicals and rational exponents using the properties of exponents.

C. Define appropriate quantities for the purpose of descriptive modeling.

D. Know there is a complex number i such that i²=-1, and every complex number has the form a + bi with a and b real.

E. Use the relation i²=-1 and the commutative, associative, and distributive properties to add, subtract, and multiply complex numbers.

F. Solve quadratic equations with real coefficients that have complex solutions.
