When dividing 3 digit number how do you know where thr first digit will be in the quotient?
The answer depends on what the divisor is. Without that information it is not possible to give a more useful answer.
Why is it important to always factor the radicand first when simplifying radicals?
The question is based on the premise that It is not possible to simplify a radical without first factorising it. That is simply not true. Beginners may find it a useful step but that does not make it "important to always factor".Simplifying radicals entails removing square factors of the radicand from under the radical. This can be done without factoring first.
What is the first step in conducting stratified sampling?

What does write an expression for the following statement mean?
It is the start of a question. A statement would then follow as part of the question. It is asking you to read that statement and carry out the instructions in the first part of the question. Without the statement it is not possible to answer the question.
How many possible area codes can you get without using 0 as the first number?
It depends on how many digits in an area code. North America (USA, Canada, etc.) uses a uniform system of 3-digit area codes, but many other countries do not. Assuming a 3-digit area code and no other restrictions other than "first digit not zero," that leaves 900 possible area codes.
