To find the quotient of \( 8 \times 10^{24} \) over \( 2 \times 10^{18} \), we can use the properties of division in scientific notation.
Let's calculate it step by step:
-
Divide the coefficients: \[ \frac{8}{2} = 4 \]
-
Subtract the exponents of the powers of ten: \[ 10^{24} \div 10^{18} = 10^{(24 - 18)} = 10^6 \]
-
Now combine the results: \[ 4 \times 10^6 \]
So, the quotient \( \frac{8 \times 10^{24}}{2 \times 10^{18}} \) in scientific notation is: \[ 4 \times 10^6 \]
