Question

UpStudy AI · Accepted Answer

To evaluate the expression $$ -3xy^{2} $$ when $$ x = 6 $$ and $$ y = -4 $$, follow these steps:

1. **Substitute the given values into the expression:**
   $$
   -3 \times 6 \times (-4)^{2}
   $$

2. **Calculate $$ y^{2} $$:**
   $$
   (-4)^{2} = 16
   $$

3. **Multiply the values together:**
   $$
   -3 \times 6 \times 16
   $$
   $$
   = -18 \times 16
   $$
   $$
   = -288
   $$

**Final Answer:** $$-288$$
When $$ x = 6 $$ and $$ y = -4 $$, the expression $$ -3xy^{2} $$ equals $$-288$$.

\( -3 x y^{2} \) when \( x=6 \) and \( y=-4 \)
