Question

1. \\(\frac{-28x^3}{7x}\\) =

Explanation:

Step1: Simplify the coefficient

Divide the coefficient \(-28\) by \(7\).
\(\frac{-28}{7} = -4\)

Step2: Simplify the variable part

Use the rule of exponents \(\frac{x^m}{x^n}=x^{m - n}\) for \(x
eq0\). Here, \(m = 3\) and \(n = 1\), so \(\frac{x^3}{x}=x^{3 - 1}=x^2\)

Step3: Combine the results

Multiply the simplified coefficient and the simplified variable part.
\(-4\times x^2=-4x^2\)

Answer:

\(-4x^2\)
