TASK 1
a
21.2 -16.8 x 0.67
Formula = (21.2-16.8)*0.67
2.948
b
5.48 + 3.8 x 1.9 /√27
Formula = (5.48 + 3.8)*( 1.9/SQRT(27))
3.393
c
(369 – 173 / 4) ÷ 68 / √83
Formula = ((369-173)/4)/(68/SQRT(83))
6.565
d
(2864 – (143 x 36)/32 ) ÷ √2568 − 121/4 x √630 − 5(89)
Formula = (2864-(143*36)/(3^2))/SQRT(2568-(121/4))*(SQRT(630-
(5*89))
618.84
e
(34.78 – (5.63)^2 ) ÷ ( √365) / 5^2
Formula = (34.78-(5.63^2))/(SQRT(365)/5^2)
4.034
