1. **Remove the dimensional prefix and express in scientific notation (include units):**

- 7.4 nm
- 6.78 x 10^8 MHz
- 5.36 x 10^6 kV
- 1500 mA

2. **Calculate the following numbers into scientific notation (include units):**

- 7800 nm + 95 pm =
- 2500 nm - 7 pm =
- (65 x 10^4 m) x (4.5 x 10^-6 s^-1) =
- (24 x 10^5 m) / (2 x 10^-8 s) =

3. **Convert the following to the prefix commonly used (use units):**

- 55,000,000 Hz
- 4.8 x 10^4 V
- 0.0068 s
- 0.00000000234 m

7.4nm = 7.4 x 10⁻⁹m 6.78 x 10^8 MHz = 6.78 x 10¹⁴ Hz 5.36 x 10^6 kV = 5.26 x 10⁹V 1500mA=1.5 A
7800nm + 95pm = 7800.095 x 10⁻⁹ m 2500nm - 7pm = 2499.993 x 10⁻⁹ m (65x10^4m) x (4.5x10^-6s-1) = 2.925 m/s (24x10^5m) / (2x10^-8s) = 1.2 x 10¹⁴ m/s (that's 400,000 'c' !)
55 000 000 Hz = 55 MHz 4.8x10^4V = 48 KV 0.0068s = 6.8 mS 0.00000000234m = 2.34 nm

7.4 x 10^9 m 6.78 x 10^11 Hz 5.36 x 10^9 V 1.5 x 10^3 mA
1nm = 10^9m and 1pm=10^11m
55MHz 48kV 234pm

The answer includes converting measurements from prefixes to scientific notation and vice versa, performing calculations in scientific notation, and expressing numbers using metric prefixes. Each step illustrates how to handle the conversions accurately and ensures understanding of the metric system. Examples and explanations clarify each transformation and calculation.
