Problem 10
Textbook Question
Perform the indicated operations. (10m4-4m2)/2m
Verified step by step guidance1
Start by writing the expression clearly: \(\frac{10m^4 - 4m^2}{2m}\).
Recognize that the numerator is a difference of two terms, so you can split the fraction into two separate fractions: \(\frac{10m^4}{2m} - \frac{4m^2}{2m}\).
Simplify each fraction separately by dividing the coefficients and subtracting the exponents of like bases: For \(\frac{10m^4}{2m}\), divide 10 by 2 and subtract the exponents of \(m\) (4 - 1). For \(\frac{4m^2}{2m}\), divide 4 by 2 and subtract the exponents of \(m\) (2 - 1).
Write the simplified terms after performing the division and exponent subtraction: \$5m^{(4-1)} - 2m^{(2-1)}$.
Simplify the exponents to get the final expression in terms of powers of \(m\): \$5m^3 - 2m$.

Introduction to Algebraic Expressions
Division of Polynomials
Dividing polynomials involves dividing each term of the numerator by the denominator separately when the denominator is a monomial. This process simplifies the expression by reducing powers and coefficients accordingly.

Exponent Rules
Exponent rules govern how to handle powers during multiplication and division. Specifically, when dividing like bases, subtract the exponents (e.g., a^m / a^n = a^(m-n)), which is crucial for simplifying terms in polynomial division.
