Final Answer :
C
Explanation :
First, simplify the numerator and denominator separately using the rules of exponents:
(3x2)(3x)2(−3x2)(3x)=27x4−9x3=−3x\frac{(3x^2)(3x)^2}{(-3x^2)(3x)} = \frac{27x^4}{-9x^3} = -3x(−3x2)(3x)(3x2)(3x)2=−9x327x4=−3x
Now the expression becomes:
(−3x)3=−27x3(-3x)^3 = -27x^3(−3x)3=−27x3
Therefore, the answer is C.
(3x2)(3x)2(−3x2)(3x)=27x4−9x3=−3x\frac{(3x^2)(3x)^2}{(-3x^2)(3x)} = \frac{27x^4}{-9x^3} = -3x(−3x2)(3x)(3x2)(3x)2=−9x327x4=−3x
Now the expression becomes:
(−3x)3=−27x3(-3x)^3 = -27x^3(−3x)3=−27x3
Therefore, the answer is C.
