Math: Simplifying a radical (aka root) expression
For this math tutor, the end-of-semester rush is about to end. Tutoring for exam prep, you tend to return to those “messy” problems students would rather avoid…. Radical expressions are among the most difficult topics in high school math. Let’s …

Math: simplification with a rational exponent
Tutoring math, this topic is perennial. The math tutor works an example. Imagine you are posed the following question: Simplify 32^(6/5) First, realize the following: 32^(6/5)=5√(32)^6 5√(32)=2, since 2*2*2*2*2 = 2^5 = 32. Therefore, 32^(6/5)=5√(32)^6=2^6=64 So 32^(6/5)=64. I’ll be saying …
