Final answer:
The expression (-4)/t² evaluated at t=-2 is simplified by squaring t to get 4 and dividing -4 by this result, yielding an answer of -1.
Step-by-step explanation:
The student asked the question: Evaluate the expression for t=-2. Simplify your answer. (-4)/ᵀ². When substituting t = -2 into the expression (-4)/t², we need to square the value of t and then divide -4 by the result. Here are the steps to evaluate:
- First, calculate t², which is (-2)² = 4.
- Next, divide -4 by t²: (-4)/4 = -1.
Therefore, the simplified answer is -1.
