Teaching might even be the greatest of the arts since the medium is the human mind and spirit." Are you really that old? 🙂

Hi there! This is very helpful thank you ! :) Quick question: For the last problem you solved (square root of 3 x cube root of 2) Why can't we add the numerators of the fractions once we have the same denominator of 6? (When we converted the equation to a mixed number) Is it because we don't have the same bases? (3^3/6 and 2^2/6) Thanks!

@FortBendTutoring 7 жыл бұрын

+SUmmer Benz That's correct. The bases must be the same.

@FortBendTutoring 11 жыл бұрын

You're always attempting to simplify by the index (root) of the problem. So if the index is 2 (a square root), you're going to find the largest multiple of 2. If it's a cube root (root 3), you're looking for the largest multiple of 3 within the exponents.

@boxbuyer2008 11 жыл бұрын

So any odd number exponents, we simply find the closest even number?

@rubyfire3377 8 жыл бұрын

How do you find the cubed root of a number? That's kind of confusing on how you got those numbers. +Fort Bend Tutoring

@FortBendTutoring 8 жыл бұрын

+Ruby Fire Calculator, prime factorization or memorization of the perfect cubes. Usually, finding a number's prime factorization will help you the most when simplifying square roots and cube roots.

@jeffsellers3497 8 жыл бұрын

As always, fantastic explanations! On example 2, do we need to include absolute value around the x^3 & y^3 to ensure they're not negative (since the index is even & the result is an odd exponent)?

@FortBendTutoring 8 жыл бұрын

As shown in the beginning of problem 2, we're assuming all variables have values that are greater than or equal to zero. Therefore, absolute value signs are unnecessary 4 these examples. However, other problems you encounter may not have those restrictions and will require absolute value signs around the solution.
