Perform the following operation and express the answer in correct scientific notation.

[tex]\[ \frac{9 \times 10^2}{3 \times 10^{12}} \][/tex]

[tex]\[ = [?] \times 10^{[?]} \][/tex]

Sagot :

Let's perform the division and express the resulting quotient in correct scientific notation.

### Step-by-Step Solution:

1. Write down the given values:
[tex]\[ 9 \times 10^2 \div 3 \times 10^{12} \][/tex]

2. Simplify the coefficients:
Divide the coefficients (i.e., the numerical parts):
[tex]\[ \frac{9}{3} = 3 \][/tex]

3. Subtract the exponents:
Using the property of exponents for division, [tex]\( 10^a \div 10^b = 10^{a - b} \)[/tex]:
[tex]\[ 10^2 \div 10^{12} = 10^{2 - 12} = 10^{-10} \][/tex]

4. Combine the simplified coefficient with the resulting power of ten:
The result then is:
[tex]\[ 3 \times 10^{-10} \][/tex]

Thus, the quotient of [tex]\( 9 \times 10^2 \div 3 \times 10^{12} \)[/tex] is expressed in correct scientific notation as:
[tex]\[ 3.0 \times 10^{-10} \][/tex]

This is already in scientific notation form, with the coefficient between 1 and 10 and the exponent indicating the power of ten.
