Adding and Subtracting Radical Expressions With Square Roots and Cube Roots

This algebra video tutorial explains how to add and subtract radical expressions with square roots and cube roots all with variables and exponents. You need to simplify the radical expressions before adding or subtracting the radical expressions. The number inside the square root must be the same before you can add or subtract the coefficients.

A very good teacher. I am very glad that I can listen to such a teacher. I am also glad that I can have an online teacher who can explain to me step by step and understand so well and quickly at the same time. For new students, you are a great help. All the best.🎉 (please like😅)

this 11:19 minute vid helped me more than 3 whole hours w/ my math teacher *facepalms*

[@filipborin555]

For these expressions witch looks like (a+b)^2 we can use a formula directly like a^2+2ab+b^2 for (a-b)^2 is a^2-2ab+b^2

[@boop6816]

what is that

Will there be a difference if we write the simplified numbers under one root? -1:48

Do you mean to write 3√4×2 - 5√9×2 if yes then Yes you can write it

Why do i get an answer of "208 sqrt of 3 + 8" instead of the answer at 10:54, using (a+b)^3 = a^3 + 3a^2b + 3ab^2 + b^3 ??

[@CYC10N3_Gaming]

On 5:55 why can you multiply the square root of 3 by 4 but not the square root of 7, they're both in the radical while 4 is outside of it?

[@korosenaiGames]

can someone please explain why at 6:45 the foil isnt going from the inner left (3) to the other 3 but instead doing something that isnt foil. i thought foil was far right to far left, far right to far right, then the two middles, and middle left to the very first. what is going on

[@prashantsharma1618]

I don't understand what your doubt Is but you can use a formula for that equation it will be easy for you to understand

[@prashantsharma1618]

Use (A)²-(B)² Let A=3 and B=√5 as given in the equation👍
