Add 6 + 3 for the numbers; then multiply 2 x 4 to get the exponent for x.

You cannot simplify this expression because these are not like terms.

Multiply 6 x 3 for the numbers; then multiply 2 x 4 for the exponent on x.

Multiply 6 x 3 for the numbers; then add 2 + 4 for the exponent on x.

I would go with the last option:

Multiply 6 x 3 for the numbers; then add 2 + 4 for the exponent on x.

This would simplify to 18x^6.
