Question

Express each of the following as a product of prime factors only in exponential form: (i) 120 x 192 (ii) 729 x 64 (iii) 27/125

Answer 1

Answer:

120=2*2*2*3*5

192=2*2*2*2*2*2*3

so 102*192=2^8*3^2*5^1

729=3*3*3*3*3*3

64=2*2*2*2*2*2

so 729*64=2^6*3^6

27=3*3*3

125=5*5*5

so 27/125=3^3*5^3
