Alg 2 :Journal entries for 4th grading period Explain the rules for simplifying a rational exponent. Write the square as a multiplication Add the exponents. Simplify. Why are rational exponents helpful ? Explain They are helpful because you can multiply them to simplify the equation Why do you think extraneous roots occur ? I think entraneous roots occur because Why do you think we need complex numbers ? We need complex numbers because if there can be imaginary numbers that we do not know about and we need to show these numbers in such a way. What are the rules for canceling in a complex number ? The rule for canceling is that if it’s the letter I then it equals the square root of -1. If its i2 then it equals -1. If its i3 then it is equal to –i. And if its i4 then it is equal to 1. Give 10 examples of a parabola. A the arch of a bridge, a bowl, a pencil, satellite dishes, water leaving a garden hose, golf, volleyball, football, and a neck lace.
