It is often useful to look at a surd in exponential notation as it allows us to use the exponential laws we learnt in Grade 10. In exponential notation, n p a= a n 1 and n p b= b1n. Then, n p an p b = a n 1 b 1 n = (ab) 1 n = n p ab (2) Some examples using this law: 1. 3 p 16 p 4 = 3 p 64 = 4 2. p 2 p 32 = p 64 = 8 3. p a2b3 2 p b5c4 = p a2b8c4 ... ................
