Answer:
[tex]12a^{7}b^{9}[/tex]
Step-by-step explanation:
The laws of exponents state that when multiplying exponents of the same base, you can add the exponents. Therefore, [tex]a^{3}*a^{6}=a^{3+6}[/tex], or [tex]a^{9}[/tex]. Same with the b's. [tex]b^{2}*b^{5}=b^{7}[/tex]. Multiplying 4*3 is easy; 12. Multiply all together and you get [tex]12a^{9}b^{7}[/tex].
