Answer:
(-0.5)² = 0.25 & (-2/3) = 0.445
Step-by-step explanation:
(-0.5)²
= (-0.5)*(-0.5)
= 0.25
(The square of 5 is 25. And (-0.5)² can be written as (-1)²*(0.5)², square of (-1) is always positive.)
&, (-2/3)²
= (-2/3)*(-2/3)
= 4/9
= 0.444
but the round off value is 0.445
( The square of 2 is 4 and the square of 3 is 9)
