Question

....... ............ dau 55 puncte​

Answer 1

Răspuns:

a=1   b=4 => a<b

Explicație pas cu pas:

a=((10/4+5/4-3/4)/5+2/5)^5

a=((12/4)/5+2/5)^5

a=(3/5+2/5)^5

a=(5/5)^5

a=1^5

a=1

b=(2/3+3/2)/7/12-(10/3*3-3* 10/3+3/2 / 1/4)

b=(5+5/6)*12/7-(3/2*4)

b= 5 5/6*12/7-6

b=35/6*12/7-6

b=5*2-6

b=4
