Exponents and Radicals-Review

(vegetable)^(1/2) = root vegetable? The fourth installment of a 35-part module has scholars extend properties of exponents to rational exponents to solve problems. Individuals use these properties to rewrite radical expressions in...

Explaining scientific notation is useful because "it allows us to write really large or really small numbers in ways that are easy for our brains to write down and understand," Sal proceeds to solve a few practice problems involving...

Scientific notation is defined and used to express the number 0.0000000003457. This concept is not as clearly defined as it could be, and is probably not suitable for those who have not had prior experience with the concept.

Apply the concept of scientific notation to a word problem involving the rate of speed. Sal explains how to express the answer in scientific notation.

Sal uses a TI-85 graphing calculator to demonstrate how to check his work while he solves a complex word problem where he must use scientific notation to express his answer. This would be a very useful video for an SAT prep or cumulative...

"Demystifying" an often mysterious problem, Sal demonstrates some tricks for considering exponents intuitively, rather than working them out each time. He first takes viewers through positive exponents and works up to negative exponents,...

A series of problems involving exponent properties is the focus of this video. Sal demonstrates rational expressions, simplifying fractions, and how to manipulate algebraic equations using exponents and division.

Bringing it all together in this video, Sal incorporates the concepts from previous lectures (quadratic formula, multiplying polynomial expressions, radical expressions, exponents). This video would be a great way to end a unit or review...

Investigate rational exponents in this math activity. Scholars make conjectures about the relationship between rational exponents and radicals. They then use their Ti-Nspire to simplify rational exponents.

This 2-part tutorial investigates exponents and radicals. Students learn about the concepts through class notes and practice problems. Topics include types of exponents, rational form, and exponential form. Radicals are discussed in Part...
