Explanation:

For 850000:

Step1: Recall significant figure rules

Significant figures: Non - zero digits are significant. Trailing zeros in a whole number without a decimal are ambiguous, but here 8 and 5 are non - zero. So we count the non - zero digits.
850000 has two non - zero digits (8 and 5) that are significant (the trailing zeros may be placeholders). So the number of significant figures is 2.

For 1101.00:

Step1: Recall significant figure rules

All non - zero digits are significant. Zeros between non - zero digits are significant. Trailing zeros after a decimal are significant.
Digits: 1, 1, 0, 1, 0, 0. Non - zero digits (1,1,1) and the zero between non - zeros (the middle 0) and the trailing zeros after decimal are significant. So count: 1,1,0,1,0,0. Total of 6 significant figures.

For 4330:

Step1: Recall significant figure rules

Non - zero digits (4,3,3) are significant. The trailing zero may be a placeholder (since no decimal). So we count the non - zero digits. 4,3,3 are significant. So number of significant figures is 3.

For 7080.0:

Step1: Recall significant figure rules

Non - zero digits (7,0,8) - the zero between 7 and 8 is significant. Trailing zeros after decimal are significant. Digits: 7,0,8,0,0. Count: 7,0,8,0,0. So number of significant figures is 5.

Answer:

s:
850000: 2
1101.00: 6
4330: 3
7080.0: 5
