ECN437 Manipulating Fractional Exponents To simplify expressions involving fractional exponents, it is helpful to  remember the following rule about exponents: (X  a ) b  = X  a*b For example: (X  2 ) 3  = X  2*3  = X  6 When a fractional exponent appears on a variable on one side of an  equation, you can often exploit this property to simplify the equation. For

Unformatted text preview: example, suppose you had the equation: L 0.3 = 10 You could raise each side to the power 1/0.3: (L 0.3 ) 1/0.3 = 10 1/0.3 Applying the above property of exponents to simplify the left hand side: (L 0.3 ) 1/0.3 = L 0.3*(1/0.3) = L Thus, the original equation can be rewritten: L = 10 1/0.3...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
