To divide \(8 \times 10^{24}\) by \(2 \times 10^{18}\), you can split it into two parts: the coefficients (8 and 2) and the powers of ten.
-
Divide the coefficients: \[ \frac{8}{2} = 4 \]
-
Subtract the exponents on the powers of ten: \[ 10^{24} \div 10^{18} = 10^{(24 - 18)} = 10^{6} \]
Now, combine the results: \[ 4 \times 10^{6} \]
So, \( \frac{8 \times 10^{24}}{2 \times 10^{18}} = 4 \times 10^{6} \).
