Final answer:
The standard form of the given expression is undefined.
Step-by-step explanation:
To find the standard form of the expression (2+31)(4-71)/(1-1), we need to simplify it step by step:
- Simplify the numerator: (2+31)(4-71) = 33*(-67) = -2211
- Simplify the denominator: (1-1) = 0
- Divide the numerator by the denominator: -2211/0
Since division by zero is undefined, the expression is undefined. Therefore, the answer is none of the given options.
