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.

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

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 ??

Thanks a ton i like the last problem makes u think this is why i like math also i wrote the last answer the reverse way does it matter i wrote 240 square 3 plus 296 instead of vise versa

[@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👍

[@prysm6925]

thanks

[@bhavana.n6611]

7:00 for this you can use a formula a^2-b^2

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?

how about square root of x+1 added to square root of x-1?

I have doubt like can we add the radicals like If 2 root 2 plus root 2 😞😅????
