to simplify this expression, 6x^(4)*3x^(2) which would be the correct steps?

a. add 6+3 for the numbers then multiply 2 x 4 to get the exponent for x
b. multiply 6 x 3 for the numbers then multiply 2 x 4 for the exponent on x
c. Multiply 6 x 3 for the numbers then add 2 + 4 for the exponent on x
d. you cannot simplify this expression because these are not like terms

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

The correct steps would be to first multiply the coefficients 6 and 3 to get 18. Then, add the exponents by multiplying 4 and 2 to get 8. Therefore, the simplified expression is 18x^(8).
