To divide two numbers in scientific notation, you divide their coefficients and subtract the exponent of the divisor from the exponent of the dividend. Here, $6 \div 24 = 0.25$ and $(-2) - (4) = -6$, so the answer is $0.25 \times 10^{-6}$, which simplifies to $2.5 \times 10^{-7}$.

Use Scientific Notation to Perform the Following Operations (6×10−2)÷(24×104)\left( 6 \times 10 ^ { - 2 } \right) \div \left( 24 \times 10 ^ { 4 } \right)(6×10−2)÷(24×104)
