Answer

25mn−4m+2n2^{5mn - 4m + 2n}

Step-by-step solution

5 steps
  1. Rewrite all bases as powers of 2.

    We know that 16=2416 = 2^4 and 8=238 = 2^3.
    Substitute these into the expression:

    2mn×(24)mn(23)m−n×2m+n\frac{2^{mn} \times (2^4)^{mn}}{(2^3)^{m-n} \times 2^{m+n}}
  2. Apply the exponent rule (ab)c=abc(a^b)^c = a^{bc}.

    2mn×24×mn23×(m−n)×2m+n\frac{2^{mn} \times 2^{4 \times mn}}{2^{3 \times (m-n)} \times 2^{m+n}} 2mn×24mn23m−3n×2m+n\frac{2^{mn} \times 2^{4mn}}{2^{3m-3n} \times 2^{m+n}}
  3. Apply the exponent rule ab×ac=ab+ca^b \times a^c = a^{b+c} to combine terms in the numerator and denominator.

    Numerator:

    2mn×24mn=2mn+4mn=25mn2^{mn} \times 2^{4mn} = 2^{mn + 4mn} = 2^{5mn}

    Denominator:

    23m−3n×2m+n=2(3m−3n)+(m+n)=23m−3n+m+n=24m−2n2^{3m-3n} \times 2^{m+n} = 2^{(3m-3n) + (m+n)} = 2^{3m-3n+m+n} = 2^{4m-2n}

    The expression now is:

    25mn24m−2n\frac{2^{5mn}}{2^{4m-2n}}
  4. Apply the exponent rule abac=ab−c\frac{a^b}{a^c} = a^{b-c}.

    25mn−(4m−2n)2^{5mn - (4m-2n)}
  5. Simplify the exponent.

    25mn−4m+2n2^{5mn - 4m + 2n}
