what is the product?\n$(4x)(-3x^{8})(-7x^{3})$\n$\\bigcirc -84x^{12}$\n$\\bigcirc -84x^{24}$\n$\\bigcirc 84x^{12}$\n$\\bigcirc 84x^{24}$
Answer
Explanation:
Step1: Multiply the coefficients
Multiply (4), (-3), and (-7). (4\times(-3)\times(-7)=4\times21 = 84)
Step2: Apply the rule of exponents for multiplying powers with the same base
For (x\times x^{8}\times x^{3}), use the rule (a^{m}\times a^{n}=a^{m + n}). (x^{1+8 + 3}=x^{12})
Answer:
(84x^{12}) (the third option)
