6*7=42 42+1=43 therefore the number you are looking for is 7
E^(∞): This is defined as 'e' being raised to a huge value. Hence the result will definitely be a large number which is also infinity (∞), i.e. e^(∞) = ∞.
e^(- ∞) = 1/e^(∞) = 1/∞ = 0.
Step-by-step explanation:

15,000 divided by 7 is greater than 800 but this question could have a number of possible answers
