Explanation:
34.95 240.016 + 23.98 -------- 298.946 --------
3.14 x 106 = 3.14 x 1000000 = 3140000.
Answer: Option D
0.2 = 0.222...;
(0.2)2 = 0.04.
0.04 < 0.2 < 0.22....<5.
Since 0.04 is the least, so (0.2)2 is the least.
Answer: Option B
Sum of decimal places = 7.
Since the last digit to the extreme right will be zero (since 5 x 4 = 20), so there will be 6 significant digits to the right of the decimal point.
