Add (9.3x10^3) + (9.3x10^4) + (0.011x10^6) using correct significant figures?

Answer 1

9.3 * 10 ^ 3 = 9.3 * 1,000 = 9,300

9.3 * 10 ^ 4 = 9.3 * 10,000 = 93,000

0.011 * 10 ^ 6 = 0.011 * 1,000,000 = 11,000

9.3 * 10 ^ 3 + 9.3 * 10 ^ 4 + 0.011 * 10 ^ 6 =

9,300 + 93,000 + 11,000 = 113,300 =

1.133 * 10 ^ 5
