Answer: [tex]30b^{3}y[/tex]
Step-by-step explanation:
1. To find the least common multiply of [tex]6b^{3}[/tex] and 15y, you must descompose 6 and 15 into their prime factors, as you can see below:
6=3*2
15=3*5
2. Choose the common and non common numbers with their greastest exponents:
3*2*5=30
Therefore, you can conclude that the least common multiply of [tex]6b^{3}[/tex] and [tex]15y[/tex] is:
[tex]30b^{3}y[/tex]
