love this guy, my college professor hasn't taught us anything, she really just solves problems, she doesn't really teach us or help us understand... thank you Brian

The students are helpful too, couldn't have understood it if they hadn't asked those questions.

Thank you so much again and again. All love from South Africa ✨

As a comment, the ‘I’ after the radical could easily be mistaken as being under the radical. I’ve usually see them written before the radical, unless @n exp it multiplication symbol is used.

This was really helpful. Thanks for making this.

I get why this works, but why must you simplify the square root first? I have checked three different levels of math texts and none describe the product property as one radicand must be positive. Is there a "must" for this, or is it just a because we said so? I see that you get different answers if you don't simplify the i out first, but why must you? Why is one more correct than the other?

Thanks! Your video helped me in order to solve a problem.

Why did you take two out of the square root. The numbers I’m working with rn are a little bigger and I’m not sure if you halfed the 4 or squared it.
