Answer:
i) 75.8
ii) 997,002
Step-by-step explanation:
Each of these expressions can be rewritten to make evaluation a little easier.
<h3>i)</h3>
The difference of squares can be factored.
a^2 -b^2 = (a -b)(a +b)
8.79^2 -1.21^2 = (8.79 -1.21)(8.79 +1.21) = (7.58)(10) = 75.8
__
<h3>ii)</h3>
The values are near 1000, so can be expressed as differences from that number.
(999)(998) = (1000 -1)(1000 -2) = 1000^2 -3(1000) +2) = 997,002
