Pull out your reference sheet that has the Pascal's Triangle.
Step 1) Locate the row that starts with 1, 8, ... If this row isn't shown, then you'll need to find a bigger Pascal's Triangle.
Step 2) Count out exactly five spaces starting at the first value 1. Why five? Because we start at 0 instead of starting at 1. The first value in the row represents
while the second value in that row represents 
and the third value represents 
and so on. So the value 
is in the fifth slot from the left.
You should land on the value 70, which is the final answer
