Step-by-step solution

2 steps

Here are the solutions to the problems.

1) a)

  1. Find the prime factorization of the numerical coefficients.

    144=24×32144 = 2^4 \times 3^2 81=3481 = 3^4

    The greatest common divisor (GCD) of 144 and 81 is the product of the lowest powers of their common prime factors.

    GCD(144,81)=32=9\text{GCD}(144, 81) = 3^2 = 9
  2. Find the GCD of the variable parts.

    For xx: The terms are x3x^3 and x1x^1. The lowest power is x1x^1.
    For yy: The terms are $y^2
