Q. Which of the expressions are equivalent to 4(3+5)−3×92 4(3+5)-3 \times 9^{2} ?\newlineSelect THREE correct answers.\newline12+20−243 12+20-243 \newline14⋅81 14 \cdot 81 \newline17−(27)2 17-(27)^{2} \newline4(8)−3×81 4(8)-3 \times 81 \newline12+20−54 12+20-54 \newline32−3⋅81 32-3 \cdot 81
  1. Simplify Parentheses: Simplify inside the parentheses: 4(3+5)4(3+5)
  2. Simplify Exponent: Simplify the exponent: 929^{2}
  3. Multiply Result: Multiply the 33 by the exponent result: 3×813 \times 81
  4. Subtract Results: Subtract the second result from the first: 32−24332 - 243
  5. Check Against Options: Check the options against our result: −211-211
