To factor the expression \(30a^3 + 40a^5\), we first need to identify the greatest common factor (GCF) of the coefficients and the variable terms.

  1. The coefficients are 30 and 40. The GCF of 30 and 40 is 10.
  2. The variable terms are \(a^3\) and \(a^5\). The GCF for \(a^3\) and \(a^5\) is \(a^3\).

Now, we can factor out \(10a^3\) from the original expression:

\[ 30a^3 + 40a^5 = 10a^3(3 + 4a^2) \]

Therefore, the correct response is:

10 a superscript 3 baseline left parenthesis 3 plus 4 a superscript 2 baseline right parenthesis.
