Final answer:
To write the expression 4x^3/7 in radical form, it can be expressed as the seventh root of 4 times the seventh root of x cubed.
Step-by-step explanation:
To write the expression 4x3/7 in radical form, we need to convert it to a rational exponent. The exponent 3/7 tells us to take the seventh root of x cubed. Therefore, the expression can be written as the seventh root of 4 times the seventh root of x cubed. In radical form, it is expressed as ∛4∛(x3).
