Express the number apperaring in the following statements in standard form.
Speed of light in vacuum is `3000,000,00 m"/"s`.

Answer

To express the speed of light in vacuum, which is given as `300,000,000 m/s`, in standard form, we will follow these steps:

### Step 1: Identify the number
The number given is `300,000,000`.

### Step 2: Write the number in scientific notation
To convert this number into scientific notation, we need to express it as a product of a number between 1 and 10 and a power of 10.

- We can write `300,000,000` as `3.0 × 100,000,000`.

### Step 3: Convert `100,000,000` to a power of 10
Now, we need to express `100,000,000` in terms of powers of 10.

- `100,000,000` can be expressed as `10^8` because `10^8 = 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10` (which is 8 zeros).

### Step 4: Combine the results
Now we can combine the results from Steps 2 and 3:

- Therefore, `300,000,000` can be expressed as:
\[ 3.0 × 10^8 \]

### Final Answer
Thus, the speed of light in vacuum in standard form is:
\[ 3.0 × 10^8 \text{ m/s} \]
