Question

If two positive integers a and b are written as a=x3y2 and b=xy3;x,y are prime numbers,then verify lcm (a,b) x hcf (a,b)=ab. From which chapter is this question from

Answer 1

Answer:

this is from chapter -1

a=x3y2

b=xy3

lcm=x3y3

hcf=xy2

to verify lcm[hcf]= a[b]

[x3y3][xy2] = x3y2[xy3]

x4y5=x4t5

hence proved
