Find the difference and express your answer in scientific notation. \( \left(5.2 \times 10^{6}\right)-\left(6 \times 10^{4}\right) \) Difference:

To find the difference \( \left(5.2 \times 10^{6}\right)-\left(6 \times 10^{4}\right) \), we first convert \( 6 \times 10^{4} \) into a form that can be subtracted from \( 5.2 \times 10^{6} \). This is done by expressing \( 6 \times 10^{4} \) in terms of \( 10^{6} \): \[ 6 \times 10^{4} = 0.06 \times 10^{6} \] Now, we can perform the subtraction: \[ 5.2 \times 10^{6} - 0.06 \times 10^{6} = (5.2 - 0.06) \times 10^{6} = 5.14 \times 10^{6} \] So, the difference is: \[ \boxed{5.14 \times 10^{6}} \]
