Answer: The required expression is \(3-5x\).
Step-by-step explanation: We are given to write the following expression :
"the difference of 3 and 5 times a number".
Let the number be represented by x.
Then, 5 times x is written as 5x.
The difference of 3 and 5 times x ca be written as
\(3-5x\).
Thus, the required expression is \(3-5x\).
