1. Write each of the following in scientific notation: a) 180000000 b) \( 0.000143 \) 2. Which number in each of the following pairs is larger? (Circle your choice) a) \( 4.9 \times 10^{-3} \) or \( 5.5 \times 10^{-6} \) b) \( 2.5 \times 10^{4} \quad \) or \( 1.2 \times 10^{6} \) c) \( 1250 \quad \) or \( 3.4 \times 10^{2} \) 3. Each of the following quantities is written in incorrect scientific notation format. Write the corrected form in the space provided: a) \( 215 \times 10^{-8} \) b) \( 0.00482 \times 10^{12} \) c) \( 41.2 \times 10^{-6} \) 4. Perform the following operations: a) \( (0.065)\left(6.023 \times 10^{23}\right)= \) b) \( \frac{\left(1.45 \times 10^{8}\right)\left(2.3 \times 10^{-3}\right)}{2.15 \times 10^{12}}= \) c) \( \frac{\left(1.0 \times 10^{-4}\right)\left(2.65 \times 10^{-3}\right)}{\left(8.35 \times 10^{-5}\right)\left(1.48 \times 10^{-2}\right)}= \)
