Question

ections: Write your answer in the box. Evaluate the expression if $$ s=2 $$ and $$ t=5 $$. Write your solution in the box. $$ -4 s^{2}+t^{3} \div 5 $$

UpStudy AI · Accepted Answer

To evaluate the expression $$-4 s^{2} + \frac{t^{3}}{5}$$ when $$ s = 2 $$ and $$ t = 5 $$, follow these steps:

1. **Substitute the given values into the expression:**
   $$
   -4 (2)^{2} + \frac{(5)^{3}}{5}
   $$

2. **Calculate the exponents:**
   $$
   -4 (4) + \frac{125}{5}
   $$
   $$
   \text{(Since } 2^2 = 4 \text{ and } 5^3 = 125\text{)}
   $$

3. **Perform the multiplication and division:**
   $$
   -16 + 25
   $$
   $$
   \text{(Since } -4 \times 4 = -16 \text{ and } \frac{125}{5} = 25\text{)}
   $$

4. **Add the results:**
   $$
   9
   $$

**Final Answer:** $$9$$
When $$ s = 2 $$ and $$ t = 5 $$, the expression $$-4 s^{2} + \frac{t^{3}}{5}$$ equals 9.
