    Start by plugging in 7 in for b in the expression.

    So we have 46² + (7) – 5.

    Now, PEMDAS tells you to deal with

    your exponents before multiplying.

    So 46² means 46 · 46 or 2,116.

    So we have 2,116 + (7) – 5.

    Now add 2,116 + 7 to get 2,123.

    Now subtract 5 to get 2,118.
