To simplify the expression \( \frac{8 \times 10^{24}}{2 \times 10^{18}} \), follow these steps:
-
Divide the coefficients: \( \frac{8}{2} = 4 \)
-
Subtract the exponents of 10: \( 10^{24} / 10^{18} = 10^{(24 - 18)} = 10^6 \)
Now, combine the results: \[ 4 \times 10^6 \]
Thus, \( \frac{8 \times 10^{24}}{2 \times 10^{18}} = 4 \times 10^6 \).
