Q. Simplify. Express your answer as a single fraction in simplest form. \newline9r42+9\frac{9r^4}{2} + 9
  1. Identify like terms and denominator: Identify the like terms and the common denominator.\newlineTo combine the terms into a single fraction, we need a common denominator. The first term has a denominator of 22, and the second term, 99, can be thought of as 91\frac{9}{1}. The common denominator for 22 and 11 is 22.
  2. Convert integer to common fraction: Convert the integer to a fraction with the common denominator.\newlineTo convert 99 to a fraction with a denominator of 22, we multiply both the numerator and the denominator by 22.\newline9×(22)=1829 \times \left(\frac{2}{2}\right) = \frac{18}{2}
  3. Rewrite expression with common denominator: Rewrite the expression with the common denominator.\newlineNow we rewrite the original expression with both terms over the common denominator of 22.\newline9r42\frac{9r^4}{2} + 182\frac{18}{2}
  4. Combine fractions: Combine the fractions.\newlineSince both terms now have the same denominator, we can combine them into a single fraction.\newline(9r4+18)/2(9r^4 + 18)/2
  5. Check for further simplification: Check if the fraction can be simplified further.\newlineThe numerator 9r4+189r^4 + 18 has a common factor of 99, but the denominator is 22, which does not share this factor. Therefore, the fraction is already in its simplest form.
