Explanation:

First Sub - Question (Value: 170)

Step 1: Recall significant digit rules

Significant digits are the digits that carry meaning contributing to the precision of a number. For non - decimal numbers:

• Non - zero digits are always significant.
• Trailing zeros in a whole number without a decimal point may or may not be significant. In the number 170, the non - zero digits 1 and 7 are significant. The trailing zero is not considered significant because there is no decimal point to indicate that it is a significant figure.

Step 2: Count the significant digits

The non - zero digits 1 and 7 are significant, so we count them.

Step 1: Recall significant digit rules

For numbers with internal zeros:

• Non - zero digits are significant.
• Zeros between non - zero digits are significant.
• Trailing zeros in a whole number without a decimal point may or may not be significant. In the number 5,050, the non - zero digits 5 (first), 5 (second) are significant. The zero between the two 5s is also significant. The trailing zero is not significant as there is no decimal point.

Step 2: Count the significant digits

We have the digits 5, 0 (between the two 5s), and 5. So we count these three digits.
