05 - Cube Roots and Higher Radical Expressions - Part 1

In this lesson, you will learn how to evaluate expressions that involve cube roots and higher radicals. We will learn cube roots, 4th roots, and more by using a factor tree to write the factors down then looking for groupings of factors.

The same process is used for cubed roots and higher radicals as is used for square roots.

How to deal with rational exponents when base X is real. Bcoz laws of exponents perfectly valid when X is no-negative real number. If it is negative, sometimes laws of exponents hold or sometimes not. Please make video on it

Jason,

Where can I purchase a shirt like the one you have on here?

Another way:

nth root {b^n} = (b^n)^(1/n) = b

Wouldn't the square root of 49 be plus or minus 7? 27:48
Why would you not count (-7) as a answer as well

Also: 5 * 5 * 5 = 5^(1 + 1 + 1) = 5^(3) = 125

Jason,

You need to do video lessons on math proofs for math majors. Also, your calculus 1, 2, and 3 videos do not contain the entire course. You left out the essentials of calculus which includes proofs.

is the teacher not over explaining things here? making it boring
