Here are the simplifications for the given expressions:

Part a· 3 steps

Simplify (5pq)2(5pq)^2

  1. Apply the Power of a Product Law, which states that (xy)n=xnyn(xy)^n = x^n y^n.

    In this case, the bases are 5, pp, and qq, and the index is 2.

    (5pq)2=52p2q2(5pq)^2 = 5^2 p^2 q^2
  2. Calculate the value of 525^2.

    52=255^2 = 25
  3. Substitute the value back into the expression.

    25p2q225 p^2 q^2

    The simplified expression is:

    25p2q2\boxed{25p^2q^2}

Part b

axbxa^xb^x

Simplify (ab)x(ab)^x

  1. Apply the Power of a Product Law, which states that (xy)n=xnyn(xy)^n = x^n y^n.

    In this case, the bases are aa and bb, and the index is xx.

    (ab)x=axbx(ab)^x = a^x b^x

    The simplified expression is:

    axbx\boxed{a^xb^x}
