Transcript
Ex 13.2, 4 Express each of the following as a product of prime factors only in exponential form: (iii) 729 × 64 729 × 64 3|729 3|243 3|81 3|27 3|9 3|3 |1 2|64 2|32 2|16 2|8 2|4 2|2 |1 ∴ 729 = 3 × 3 × 3 × 3 × 3 × 3 = 36 ∴ 64 = 2 × 2 × 2 × 2 × 2 × 2 × 2 = 26 So, 729 × 64 = 36 × 26 = 26 × 36
