Final answer:
To simplify 3x^(3)*x^((3)/(4)), multiply the coefficients and add the exponents. The simplified expression is 3 * x^((15)/(4)).
Step-by-step explanation:
To simplify the algebraic expression 3x^(3)*x^((3)/(4)), we need to multiply the coefficients and add the exponents of the variable.
3x^(3)*x^((3)/(4))
= 3 * x^(3+3/4) (using the rule of multiplying coefficients and adding exponents)
= 3 * x^((12+3)/(4)) (combining the exponents)
= 3 * x^((15)/(4))
Therefore, the simplified expression is 3 * x^((15)/(4)).
