Answer:

The result for the equation is $\frac{b^6}{3}$

Step-by-step explanation:

Solve the equation:

$7b^3$ × $b^4$

--------

$21b$

-When you multiply both integers with exponents, the exponents will add up together:

$\frac{7b^7}{21b}$

-Then, you simplify:

$\frac{7b^7}{21b}=\frac{b^6}{3}$

So, therefore, the result for the equation is $\frac{b^6}{3}$ .
