Question

Evaluate the following expressions by substituting s = 10 and t = 2.
3t2s

Answer 1

To evaluate the expression \( 3t^2s \) with the values \( s = 10 \) and \( t = 2 \), we can follow these steps:

1. Substitute the values of \( t \) and \( s \) into the expression:
\[
3(2^2)(10)
\]

2. Calculate \( 2^2 \):
\[
2^2 = 4
\]

3. Substitute \( 4 \) back into the expression:
\[
3(4)(10)
\]

4. Multiply \( 3 \) and \( 4 \):
\[
3 \times 4 = 12
\]

5. Now multiply \( 12 \) by \( 10 \):
\[
12 \times 10 = 120
\]

Thus, the value of the expression \( 3t^2s \) when \( s = 10 \) and \( t = 2 \) is \( \boxed{120} \).
