If a,b,c are the 3 positive integers
1/a +1/b +1/c > 6/abc
(bc+ac+ab)/abc >6/abc so
(bc+ac+ab)>6
The lowest positive integers that are different are 1,2,3 so the lowest value that (bc+ac+ab) could have is 1•2+2•3+1•3=2+6+3= 11 therefore
1/a +1/b +1/c > 6/abc is true
The answer is 2 3/10. how do you not know this
Answer:
(4.2x100).(5.7x100) = 239.400
Step-by-step explanation:
We need to determine the product of (4.2x100).(5.7x100).
We know that when two numbers are multiplied together, the product is the same regardless of the order of the multiplicands. For that reason, we can multiply all together, and the result will be the same regardless of the order of the multiplicands:
Then:
(4.2x100).(5.7x100) = 4.2x100x5.7x100 = 420x570= 239.400
