\(\left(-\dfrac{1}{2}\right)^2:\left(1\dfrac{5}{16}-1,5\right)+2021^0\)
\(=\dfrac{1}{4}:\left(\dfrac{21}{16}-\dfrac{24}{16}\right)+1\)
\(=\dfrac{1}{4}:\left(-\dfrac{3}{16}\right)+1\)
\(=-\dfrac{4}{3}+\dfrac{3}{3}\)
\(=-\dfrac{1}{3}\)
`(-1/2)^2 : (1 5/16 - 1,5) + 2021^0`
`= 1/4 : ( 21/16 - 1,5) +1`
`= 1/4 : (-3/16)+1`
`= 1/4 xx (-16/3) +1`
`=-4/3+1`
`= -4/3 + 3/3`
`= -1/3`
(−12)2:(1 516−1,5)+20210(-12)2:(1 516-1,5)+20210
=14:(2116−1,5)+1=14:(2116-1,5)+1
=14:(−316)+1=14:(-316)+1
=14×(−163)+1=14×(-163)+1
=−43+1=-43+1
=−43+33=-43+33
=−13 cái này làm tắt đc ạ. Em ko chắc lắm
