    A) Do you mean:

    (2e^6-\ln(|2|))-(2e-\ln(|1|)) ? If so:

    1. Expand the brackets.
    2. Keep in mind that \ln(1) = 0

    3. You'll get: 2e^6-\ln(|2|)-2e = 2e(e^5-1)-\ln(|2|)

    B) Do you mean:

    (2e^{6-\ln(|2|)})-(2e^{-\ln(|1|)}) ? If so:

    1. Expand the brackets. \ln(1) = 0 and e^0 = 1

    2. You'll get: \frac22 e^6 -2 = e^6-2
