Q. Simplify. Express your answer using positive exponents.\newline9z79z4×z3\frac{9z^7}{9z^4 \times z^3}
  1. Simplify denominator: Simplify the denominator by multiplying the powers of zz. 9z4×z3=9z4+3=9z79z^4 \times z^3 = 9z^{4+3} = 9z^7
  2. Divide numerator: Simplify the entire expression by dividing the numerator by the simplified denominator. 9z79z7=1\frac{9z^7}{9z^7} = 1
