Hi there!
The question is asking us to write an algebraic expression of four times the product of 8 and a number.
We start from the beginning. Four times something means we multiply 4 by that something. This is written as 4 × (something).
Next we see "the product of 8 and a number". We usually write "a number" as a variable. For this problem, I'll choose k.
The product of 8 and k means we multiply 8 times k, which thus gives us: 8k.
Overall, the required expression is 4 × 8k.
Have a fantastic day!
