Answer:
[tex]6b^{5}[/tex]
Step-by-step explanation:
Apply the rule: [tex](a) =a[/tex]
= [tex]b\cdot \:2b\cdot \:3b^3[/tex]
Apply exponent rule: [tex]\:a^b\cdot \:a^c=a^{b+c}[/tex]
= [tex]b^{1+1+3}\cdot \:2\cdot \:3[/tex]
Add the numbers: [tex]1+1+3=5[/tex]
= [tex]b^5\cdot \:2\cdot \:3[/tex]
Multiply the numbers: [tex]2\cdot \:3=6[/tex]
= [tex]6b^{5}[/tex]
