Q. Simplify: 5c(3c2)35c(3c^{2})^{3}\newlineA. 45c645c^{6}\newlineB. 135c6135c^{6}\newlineC. 45c745c^{7}\newlineD. 135c7135c^{7}
  1. Simplify Inside Parentheses: First, we need to simplify the expression inside the parentheses, which is (3c2)3(3c^{2})^{3}. According to the power of a power rule, we multiply the exponents when raising a power to a power.\newlineCalculation: (3c2)3=33×(c2)3=27c2×3=27c6(3c^{2})^{3} = 3^{3} \times (c^{2})^{3} = 27c^{2\times3} = 27c^{6}
  2. Multiply by Coefficient: Now, we multiply the result by the coefficient outside the parentheses, which is 5c5c.\newlineCalculation: 5c×27c6=5×27×c1+6=135c75c \times 27c^{6} = 5 \times 27 \times c^{1+6} = 135c^{7}
  3. Final Answer: We have simplified the expression and found that the correct answer is 135c7135c^{7}, which corresponds to option D.
