Pembahasan

a. (27x^3y^5z^2)/(3xy^2z) = (27/3) * (x^3/x) * (y^5/y^2) * (z^2/z) = 6 * x^(3-1) * y^(5-2) * z^(2-1) = 6x^2y^3z

b. (12ba^5b^2/32ab^4)x(2^3a^3b^5/a^7b^3) = (12/32) * (b/b^4) * (a^5/a) * (27a^3b^5/a^7b^3)
= (3/8) * b^(1-4) * a^(5-1) * 27 * a^(3-7) * b^(5-3)
= (3/8) * b^(-3) * a^4 * 27 * a^(-4) * b^2
= (3 * 27) / 8 * a^(4-4) * b^(-3+2)
= 81/8 * a^0 * b^(-1)
= 81/8 * 1 * (1/b)
= 81/(8b)
