Answer 1

a)...=1/12*4/3 + 7/6*12/1=1/9+14=14  1/9

b)...=16/10-12/10*4/3=16/10-8/5=8/5-8/5=0

c)...=-1  1/8 * 1/8 =-9/8*1/8=-9/64

d)...=24/100:(-8/10)=24/100*(-10/8)=-3/10

e)...=5/4+9/4*1/8=5/4+9/32=40/32+9/32=49/32=1 17/32

f)...=√100=10

g)...=2*3*√(3*2)=6√6

h)...=4*7*√(2*6)=28*√12=28√(4*3)=28*2√3=56√3

i)...=√(8*3) / 2=√24/2=√(4*6)/2=2√6/2=√6
