Step-by-step explanation:
There are two ways to work this out: normal variables or using "imaginary" numbers.
Normal variables:
Imaginary numbers:
Using the result from earlier:
Now since
, then the expression becomes:
Answer:
Step-by-step explanation:
We have given the numbers = 2,0,1,9
We can use addition and subtraction operation to the given numbers such that the answer will be equals to 6.
We can add 2 ,0 and 1 and then subtract from 9 , we will get 6.
So the required expression can be
hence, the required expression can be
1/100 of a metre, as 100cm make 1m
