Final answer:
The expression 1*0 results in 0. The expressions 1*(0 1) and 0*(1 0) are ambiguous without clear operator symbols, but generally indicate a multiplication by zero, which also results in 0.
Step-by-step explanation:
The question involves basic arithmetic operations and understanding of multiplication. The expressions provided are simple multiplications.
The result of 1*0 is 0 because any number multiplied by zero gives zero.
For 1*(0 1), if it's meant to be 1*0 followed by 1, the result would be 01 in a coding context or possibly 0 if we interpret the space as a separator. However, this could be a typo, and without clear spacing or operator symbols, it is ambiguous.
Similarly, for 0*(1 0), if it's meant to be 0*1 followed by 0, the result is 00 or simply 0. The presence of a space again makes the expression ambiguous.
It is important to note that without clear operator symbols, expressions with spaces can be easily misinterpreted.
