what is the product?\n(4x)(-3x^8)(-7x^3)\n-84x^12\n-84x^24\n84x^12\n84x^24

Explanation:

Step1: Multiply the coefficients

$(4)\times(-3)\times(-7)=4\times3\times7 = 84$

Step2: Use the rule of exponents $a^m\times a^n=a^{m + n}$ for $x$ - terms

$x\times x^{8}\times x^{3}=x^{1 + 8+3}=x^{12}$

Step3: Combine the results

The product is $84x^{12}$

Answer:

C. $84x^{12}$
