To simplify the expression \( 6x^4 \cdot 3x^2 \), you should follow these steps:
- Multiply the coefficients (numbers): \( 6 \times 3 = 18 \).
- Add the exponents of \( x \): Since you have \( x^4 \) and \( x^2 \), you add the exponents: \( 4 + 2 = 6 \).
So, combining these results, the simplified expression is \( 18x^6 \).
The correct response from your options is: Multiply 6 x 3 for the numbers; then add 2 + 4 for the exponent on x.
