7.7 + 7.7 = 7 7/10 + 7 7/10 = 14 + 14/10 = 14 + 1 4/10 = 15 2/5
If you mean 1/7 then it is 2/14
If you mean: 7/10 then they are 14/20 and 21/30
If you mean 10/14, then it is 5/7 or .714. If you mean 14^10, then it is 2.89254655E11.

7.7 + 7.7 = 7 7/10 + 7 7/10 = 14 + 14/10 = 14 + 1 4/10 = 15 2/5
The factors of seventy are 1, 2, 5, 7, 10, 14, 35, and 70.
The factors of 7 are: 1, 7The factors of 14 are: 1, 2, 7, 14
If you mean 1/7 then it is 2/14
ten 5/7 x 14 = 5/1 x 14/7 = 5 x 2/1 = 10
If you mean: 7/10 then they are 14/20 and 21/30
5/7 + 1/2 = 10/14 + 7/14 = 17/14 = 13/14
It is: 1
(x+y)/2=7; x+y=14; y=14-x 3=√(xy); xy=9; y=9/x Use substitution: 14-x=9/x; 14x - x2=9; x2 - 14x +9=0 Use the quadratic formula: x=[14±√(196-36)]/2; x=[14±√160]/2; x=[14±4√10]/2 x=7+2√10 or x=7-2√10 If x=7+2√10, then y=14-(7+2√10)=7-2√10 If x=7-2√10, then y=14-(7-2√10)=7+2√10 The first pair's geometric mean is √[(7+2√10)(7-2√10)]=√[72-(2√10)2]=√(49-40)=√9=3. The first pair's arithmetic mean is (7+2√10 +7-2√10)/2=14/2=7 The second pair's geometric mean is √[(7-2√10)(7+2√10)]=√[72-(2√10)2]=√(49-40)=√9=3. The second pair's arithmetic mean is (7-2√10 +7+2√10)/2=14/2=7 That's it!
