- Laws of exponents sir?
- Now that we have arrived in our classroom, let's start our discussion. The first law states that n√an= (n√a)n= a Let me give you an example (1), √x2 = (√x)2 = xI'll give you more examples for you to understand it very well.(2) 3√k3 = (3√k)3 = kCan you give me your own example for this law?

- That's great Stacy. Terrific, I must say!
- Sir, how about 10√510 = (10√5)10 = 5?
- Now that we've finished the first law, let's proceed to the second one. It states that n√ab = n√a · n√bLet me give you an example (1) √gk = √g · √kAnother example (2) 4√wb = 4√w · 4√bAs we always do, can someone give me your own example for the second law?
- Very good Kelly, thank you for participating.
- How about Kelly? can you give me your own example?
-
- Sure, sir 3√5m = 3√5 · 3√m
