Q. Subtract. Write your answer in simplest form.

\newline

9\sqrt{7} - 4\sqrt{7}

Identify like terms: Identify like terms Both terms have the same radical part, $\sqrt{7}$ , which means they are like terms and can be combined by adding or subtracting the coefficients.
Subtract coefficients: Subtract the coefficients $\newline$ Subtract the coefficient of the second term from the coefficient of the first term. $\newline$ $9\sqrt{7} - 4\sqrt{7} = (9 - 4)\sqrt{7}$
Perform subtraction: Perform the subtraction $\newline$ Calculate the difference of the coefficients. $\newline$ $9 - 4 = 5$
Write final answer: Write the final answer Combine the difference of the coefficients with the common radical part to get the final answer. $5\sqrt{7}$
