Round the following according to the correct number of significant digits. Show all work. (0.120) (8.206 X 10 -2)(273.15 +23)÷ (230/760.0)
+40 So use BOMDAS (Brackets of Multiplication, Division, Addition and Subtraction) rule to start.
Therefore you'd work out all task contained in brackets first, ie:
-> (0.120) (0.08206)(296.15) ÷ (0.30263)
(Note- all i did was to rewrite 8.206 x 10 -2 as a decimal not in standard form)
Then do all multiplications, ie:
-> 2.91624828 ÷ 0.30263
Then divide:
-> 2.91624828 ÷ 0.30263= 9. 6363
Since you didnt state the number of significant digits required, I'm just going to leave it at 5.
