Answer:
29274
Step-by-step explanation:
Because 17*14=238 and 238*123=29274
20
75=3/4
So 20/4=5
5 is 1/4 of 20 therefore 15 is 3/4 of 20 because 5x3=15.
Exponents can make the problem smaller and look less confusing. If you see a problem with 5*5*5*5*5*5*5*5 then you're going to eventually loose count and will have to keep repeating. But if you put 5 to the 8th power then you know right away just to multiply 5, (8) times,
'Which area represents elements contained in the sample space that are not contained in swimmers or weightlifters?'
