Math Problem Statement

(3a*6a^7)/a^-4

Solution

To simplify the given expression:

3a6a7a4\frac{3a \cdot 6a^7}{a^{-4}}

Step-by-Step Simplification:

  1. Multiply the terms in the numerator: 3a6a7=18a1+7=18a83a \cdot 6a^7 = 18a^{1+7} = 18a^8

  2. Simplify the division by subtracting the exponents of aa: 18a8a4=18a8(4)=18a8+4=18a12\frac{18a^8}{a^{-4}} = 18a^{8 - (-4)} = 18a^{8 + 4} = 18a^{12}

Final Answer:

18a1218a^{12}
