calculați: {[(3:10+0,12:0,6)²+2•1,2]-0,65}•0,5​

Answer 1

Răspuns:

1

Explicație pas cu pas:

[(3/10+12/100×10/6)²+24/10]-65/100}×1/2= {[(3/10+2/10)²+24/10]-65/100}1/2=

=[(25/100+240/100)-65/100]×1/2=(265/100-65/100)×1/2=200/100×1/2=1

Answer 2

Răspuns:

Explicație pas cu pas:

{[(3:10+0.2)²+2,4]-0.65}*0.5 =

={[(0.3+0.2)²+2.4]-0.65}*0.5

=[(0.25+2.4)-0.65]*0.5

=(2.65-0.65)*0.5

=2*0.5
