To evaluate ( (1.4 \times 10^5) - (6.2 \times 10^4) ), subtract the second number from the first number while keeping the exponents the same:

( (1.4 \times 10^5) - (6.2 \times 10^4) = (1.4 - 0.62) \times 10^5 )

( = 0.78 \times 10^5 )

Now, 0.78 is written in scientific notation by moving the decimal point one place to the right:

( = 7.8 \times 10^4 )

So, ( (1.4 \times 10^5) - (6.2 \times 10^4) = 7.8 \times 10^4 ).
