Write the following measurements in long form:

1. \(4.5 \times 30 \, \text{g}\)

2. \(1.99 \times 10^{-8} \, \text{cm}\)

In the first case, just multiply both values. In the second case, you must also multiply the number by itself, but to do so carefully move the comma.

4.5x30 g 2. 1.99x10-8 cm


4.5 * 30 = 135g = 0.135 kg (if you want to in kg)
1,99*0.00000001 = 0.0000000199 cm

The long form of 4.5 × 30 g is 135 grams, and the long form of 1.99 × 1 0 − 8 cm is 0.0000000199 centimeters.
