what is ?4a^6b^5c^4 x -7b^7c^6

Answer 1

To simplify the expression \( 4a^6b^5c^4 \times -7b^7c^6 \), you can multiply the coefficients and combine the variables accordingly.

1. Multiply the coefficients: \( 4 \times -7 = -28 \)

2. Combine the variables:

   • For \( b \): \( b^5 \times b^7 = b^{5+7} = b^{12} \)
   • For \( c \): \( c^4 \times c^6 = c^{4+6} = c^{10} \)

Putting it all together, we get:

\[ 4a^6b^5c^4 \times -7b^7c^6 = -28a^6b^{12}c^{10} \]

So, the simplified expression is:

\[ -28a^6b^{12}c^{10} \]
