evaluate [a 4] when [a=7].
To evaluate the expression [a 4] when [a=7], we first need to understand the context or operation implied by the placement of (a) next to (4). Typically, if it’s written as (a4), it suggests multiplication of (a) and (4).
Answer:
Given:
[ a = 7 ]
Expression to evaluate:
[ a \times 4 ]
We substitute the value of (a) into the expression:
[
7 \times 4 = 28
]
Therefore, the value of [a 4] when [a=7] is 28.
If this expression was meant differently (e.g., a function or different operation is implied), please clarify for an accurate evaluation. @username
