Where a and b are not equal and both are positive integers, use the formula:For 1/a + 1/b = 1/c1/(c + 1) + 1/(c + 1)(c) = 1/c.1/18 + 1/(18 × 17) = 1/17(The commutative law of addition obviously applies.)
A and B are indigers?
how do I know if I should add 289 to the equation ?
I wish the video explained the logic behind this. I can make a guess (17*17), but that isn't as helpful/satisfying as understanding the "why".
a=34 and b=34 is the answer because 1/34+1/34=2/34=1/17
ExactlyAlso, he needed too many steps to reach the solutionIt could be easily solved in no more than ten to twelve steps
Pretty hopeless video really
but a=306 and b=18anda=18 and b=306 are also answers
@@ralphtrucksess7008Correct. If a = b, the problem is trivial.
