The question asks to express the number 1548 in two ways:

1. **(a) To one significant figure**:
   - The first significant figure in 1548 is 1 (the first non-zero digit).
   - To express 1548 to one significant figure, we round 1548 to 1 significant figure. The next digit (5) is greater than or equal to 5, so we round up:
   \[
   1548 \approx 2000 \text{ (to one significant figure)}
   \]

2. **(b) To the nearest ten**:
   - To round 1548 to the nearest ten, we look at the units digit (8). Since 8 is greater than or equal to 5, we round the tens digit up:
   \[
   1548 \approx 1550 \text{ (to the nearest ten)}
   \]
