\( -72 \)
Solución
Substitute \( q=-3,a=-2 \) into the expression \( 4q^2a \).
Evaluate the expression by following steps:
- step0: Evaluate:
\(4q^{2}a\)
- step1: Substitute:
\(4\left(-3\right)^{2}\left(-2\right)\)
- step2: Rewrite the expression:
\(-4\left(-3\right)^{2}\times 2\)
- step3: Multiply the terms:
\(-8\left(-3\right)^{2}\)
- step4: Multiply the terms:
\(-72\)
Substitute \( q=-3 \) and \( a=-2 \) into the expression \( 4q^{2}a \), we get \( -72 \).

To evaluate \( 4 q^{2} a \) for \( q=-3 \) and \( a=-2 \), we start by substituting the values of \( q \) and \( a \) into the expression: 1. Calculate \( q^{2} \): \[ q^{2} = (-3)^{2} = 9 \] 2. Now plug \( q^{2} \) and \( a \) into the expression: \[ 4 q^{2} a = 4 \times 9 \times (-2) \] 3. Multiply to find the result: \[ 4 \times 9 = 36 \] \[ 36 \times (-2) = -72 \] Therefore, the value of \( 4 q^{2} a \) is \(-72\).
