Round 0.9976 to 2 significant figures.

Final answer: To round 0.9976 to 2 significant figures, you would get 1.0 x 10^0. Explanation: To round a number to a given number of significant figures, you need to look at the digit after the last significant figure you want to keep. If this digit is greater than or equal to 5, you round up the last significant figure. If this digit is less than 5, you simply drop all the digits after the last significant figure. In the case of 0.9976, the digit after the second significant figure (9) is 7, which is greater than 5. Therefore, you would round up the last significant figure (9) to become 10. However, since we are rounding to 2 significant figures, we need to change this to scientific notation. The final result would be 1.0 x 10^0.

Final answer: To round 0.9976 to 2 significant figures, we round up the desired significant figure by increasing it by 1.
