Answer 2

To perform the calculation, you need to multiply 678 by 10 raised to the power of -7. When raising a number to a negative exponent, it means you move the decimal point to the left by the number of places indicated by the exponent.

So, 10 raised to the power of -7 is 0.0000001 (7 zeros after the decimal point). Now, you can multiply this by 678:

678 * 0.0000001 = 0.0000678

Therefore, 678 × 10^(-7) equals 0.0000678.
