answer this please and give explanation brainliest is given

Answer:
The result for the equation is [tex]\frac{b^6}{3}[/tex]
Step-by-step explanation:
Solve the equation:
[tex]7b^3[/tex] × [tex]b^4[/tex]
--------
[tex]21b[/tex]
-When you multiply both integers with exponents, the exponents will add up together:
[tex]\frac{7b^7}{21b}[/tex]
-Then, you simplify:
[tex]\frac{7b^7}{21b}=\frac{b^6}{3}[/tex]
So, therefore, the result for the equation is [tex]\frac{b^6}{3}[/tex].
