Match the indeterminate form with the first step it calls for. 1. \( 0/0 \)   2. \( 0 \times \infty \)   3. \( 1^{\infty} \)   P. Invert one factor to make a quotient   Q. Differentiate numerator and denominator   R. Take logarithms

  • A.1-Q, 2-P, 3-R
  • B.1-Q, 2-R, 3-P
  • C.1-P, 2-Q, 3-R
  • D.1-R, 2-P, 3-Q

Answer: A

Only \( 0/0 \) and \( \infty/\infty \) are ready for L'Hopital's rule, so a quotient is differentiated at once. A product is turned into a quotient by inverting one factor, and a power is turned into a product by taking logarithms, after which the same rule finishes the work
