\][/tex]

Sagot :

Sure, let's walk through the division step-by-step and express the result in scientific notation.

We are given the following operation to perform:
[tex]\[ \frac{6.900 \times 10^{10}}{4.000 \times 10^{8}} \][/tex]

### Step 1: Divide the Coefficients
First, divide the coefficients [tex]\(6.900\)[/tex] by [tex]\(4.000\)[/tex]:
[tex]\[ 6.900 \div 4.000 = 1.725 \][/tex]

### Step 2: Subtract the Exponents
Next, we handle the powers of 10. When you divide powers of ten, you subtract the exponent of the denominator from the exponent of the numerator:
[tex]\[ 10^{10} \div 10^{8} = 10^{10 - 8} = 10^{2} \][/tex]

### Step 3: Combine the Results
Now, we combine the result of the coefficient division with the result of the exponent subtraction:
[tex]\[ 1.725 \times 10^{2} \][/tex]

### Final Answer
Expressing the result in correct scientific notation:
[tex]\[ 1.725 \times 10^{2} \][/tex]

Hence, the result of the operation [tex]\(\frac{6.900 \times 10^{10}}{4.000 \times 10^{8}}\)[/tex] is:
[tex]\[ 1.725 \times 10^{2} \][/tex]
