Resuelve las operaciones indicadas

Answer 1

a.) -2/11 + (-9/11) 
= -2/11 - 9/11
= -11/11
= -1

b.)17/5 + (-19/5)
= 17/5 - 19/5
= -2/5
= -0.4

c.)-4/6 + 7/8
= (-32+21)/24
= -11/24
=0.46

d.) -5/8 - 11/20
= (-25-22)/40
= -47/40
=-1.175

e.) 9/15 - (-7/12)
= (36+35)/60
= 71/60
=1.18

f.)7/5 * (-8/6)
= -56/30
= -28/15
=-1.86

g.) 13/6 * 4/11
= 52/66
= 26/33
= 0.7878

h.) -10/8 * (-12/20)
= 120/160
= 3/4
=0.75

i.) 15/16 * (-20/5)
= -300/80
= -15/4
= -3.75

j.) (20/12) / (25/30)
= 600/300
= 2

k.) (-25/32) / (10/16)
= -400/320
= -5/4
= -1.25

l.) (-2/9) / 8/6)
= -12/72
= -1/6
= -0.16666

m.) (2/3)³
= 2³ / 3³
= 8/27
= 0.296

n.) $9^8 / 9^6$ ( se simplifican)
= 9²
=81

ñ.)$\sqrt[4]{16/81}$
=$\sqrt[4]{16} / \sqrt[4]{81}$
= 2/ 3
=0.66
