Given:
Consider the given equation is
To find:
The missing value in the given equation and complete the equation.
Solution:
We have,
Taking LHS, we get
and,
Let the missing value be k.
For each equation LHS=RHS.
Therefore, the missing value is 10 and the complete equation is .
Answer:
43,200 serial numbers can be generated
Step-by-step explanation:
The ordering for the letters and the digits are important. For example, 012 constitutes a different serial number than 210. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
How many serial numbers can be generated
3 letters, from the first five of the alphabet
3 digits, from a set of 10
So
43,200 serial numbers can be generated
