Question

Simplify$b^{-3}\cdot b^7$ assuming that no variable equal to 0 .

Short answer

The simplified value of expression is $b^4$.

Step-by-step solution

Step 1. Write down the given expression.

The given expressiomn to simplify is $b^{-3}\cdot b^7$.

Step 2. Simplify the given expression.

Simplifying $b^{-3}\cdot b^7$ gives,

$\begin{array}{c}{b}^{-3}\cdot b^7={\left(b\right)}^{-3}{\left(b\right)}^7\\ ={\left(b\right)}^{-3+7}\\ =b^4\end{array}$

Step 3. Conclusion.

The simplified value of expression is $b^4$.
