The worksheet and quiz will test you on your ability to solve: To develop complete confidence in this area, take the time to review the lesson, How to Solve Exponential Equations. 0000034608 00000 n Mathematicians have decided to use negative Moreover, the problems give you the expected bases. inverse of the base, for example \(5^{-4}$$ is used to indicate 0000107436 00000 n This section is a quick foray into math history, and the history of polynomials! learner did the calculation correctly? Solution: Here we are essentially doing the reverse process of the last examples. exponential notation in some different ways if possible: Calculate the value of This section aims to show how mathematical reasoning is different than ‘typical Explain why. Are you sure you want to do this? | 11 In this section we cover Domain, Codomain and Range. 0000001876 00000 n Determine the value of each of Here is a walk-through example of how to do a problem like this: \frac {\left (125^{\frac {1}{3}z}\right )\left (125^{\frac {4}{5}x-\frac {5}{8}}\right )\left (25^{-5y-\frac {5}{8}}\right ) }{ \left (125^{\frac {3}{4}x+\frac {1}{2}}\right )\left (25^{-\frac {1}{3}y}\right )\left (25^{-\frac {1}{8}z-\frac {3}{8}}\right ) } (Hint: 5^2= 25, 5^3 = 125). The easiest way to do this is to simply replace the larger number with the universal base to the appropriate power in parentheses.
