1/2+ 2/3- 17/84

(1×42)/(2×42 ) = 42/84 (2×28)/(3×28 ) = 56/84

42/84 + 56/84 - 17/84 = 81/84 = 27/28


3/10+ 5/2- 7/36
(3×18)/(10×18 ) = 54/180(5×90)/(2×90 ) = 450/180 (7×5)/(36×5 ) = 35/180
54/180 + 450/180 - 35/180= 469/180

4/3- 3/4+ 1/18

(4×12)/(3×12 ) = 48/36 (3×9)/(4×9 ) = 27/36(1×2)/(18×2 ) = 2/36

48/36 - 27/36 + 2/36= 23/36

8/3 ÷ 2/5- 7/16

8/(3 ) ÷ 2/5 = 40/6 - 7/16
(40×8)/(6×8 ) = 320/48 (7×3)/(16×3 ) = 21/48
320/48 - 21/48= 299/48

7/3 × 6/5+ 27/64

7/(3 )× 6/5 = 42/15 + 27/64
(42×64)/(15×64 ) = 2688/960 (27×15)/(64×15 ) = 405/960
2688/960 + 405/960 = 3093/960 = 1031/3202/3+ 5/4- 7/2

(2×4)/(3×4 ) = 8/12 (5×3)/(4×3 ) = 15/12 (7×6)/(2×6 ) = 42/12

8/12 + 15/12 - 42/12= (-19)/12

3/6-2/5+ 4/7- 1/3

(3×35)/(6×35 ) = 105/210(2×42)/(5×42 ) = 84/210 (4×30)/(7×30 ) = 120/210 (1×70)/(3×70 ) = 70/210

105/210 - 84/210 + 120/210 - 70/210 = 71/210

Simplifique y exprese todas lasrespuestas en términos de exponentes positivos.

(2^2 ) (2^3 )= 2^5

W^4 W^3 = W^7

( X^2 X^5)/(Y^8 Y^6 ) = X^7/Y^14

(X^3 )^4/(Y^3 )^2 = X^12/Y^6

X^8/X^2 = X^(8-2)...
