✔ 最佳答案
Sub A=3 and B=4= 1/(3-1/4)
= 1/(2 3/4)
= 1/(11/4)
= 4/11
--------------------------------------------------------------------------------------------------------------------------------
Hence, we do A triangle B
and the answer is 3/5.
The process:
Sub A=2 and B=3
= 1/(2-1/3)
= 1/(1 2/3)
= 1/(5/3)
= 3/5
--------------------------------------------------------------------------------------------------------------------------------
Then sub the 3 triangle 4 and 2 triangle 3 to 4/11 and 3/5.
= (4/11)/1+(3/5)
= (4/11)/(1 3/5)
= (4/11)/(8/5)
= (4/11)x(5/8)
= 5/22

這純屬一道小一程度的數學題，
為什麼也有人答錯？

= (1 / (3-1/4)) / (1+ (2 - 1/3))
= (1/ (11/4)) / (1+ 5/3)
= (4/11)/(8/3)
=4/11 x 3/8
= 12/88
= 3/22
= (1/ (11/4)) / (1+ 5/3)

3 ^ 4= 1/ [3 - (1/4)]
=1/(11/4)
=4/11
1+2 ^ 3= 1+ {1/ [2 - (1/3) ] }
=1+ [ 1/(5/3) ]
=1+ (3/5)
=8/5
(4/11) / (8/5)
=(4/11) * (5/8)
=5/22
=1/(11/4)
=4/11
1+2 ^ 3= 1+ {1/ [2 - (1/3) ] }

since:
a^b=1/(a-1/b)
so:
3^4=1/(3-1/4)
3^4=4/11
&
2^3=1/(2-1/3)
2^3=3/5
3^4/(1+2^3)
=(4/11)/(1+3/5)
=(4/11)/(8/5)
=(4/11)(5/8)
=20/88
=10/44
a^b=1/(a-1/b)
so:
3^4=1/(3-1/4)
3^4=4/11
&
2^3=1/(2-1/3)
2^3=3/5
3^4/(1+2^3)
=(4/11)/(1+3/5)
=(4/11)/(8/5)
=(4/11)(5/8)
=20/88
=10/44
2007-11-03 12:52 am
= (1 / (3-1/4)) / (1+ (2 - 1/3))
= (1/ (11/4)) / (1+ 5/3)
= (4/11)/(8/3)
=4/11 x 3/8
= 12/88
= 3/22
= (1/ (11/4)) / (1+ 5/3)
= (4/11)/(8/3)
=4/11 x 3/8
= 12/88
= 3/22
