Quizplus · Accepted Answer

When multiplying terms with exponents, you multiply the coefficients and add the exponents if the bases are the same. Here, $7 \times 9 \times 8 = 504$ and $x^2 \times x^1 \times x^3 = x^{2+1+3} = x^6$, making the correct answer $504 x^6$.

Multiply the Following (7x2)(9x)(8x3)\left( 7 x ^ { 2 } \right) ( 9 x ) \left( 8 x ^ { 3 } \right)(7x2)(9x)(8x3)

Multiply the Following $\left( 7 x ^ { 2 } \right) ( 9 x ) \left( 8 x ^ { 3 } \right)$
