Final answer:
The radical expression equivalent to (35)^1/4 is the fourth root of 35, written as √^4 35 or 35^1/4.
Step-by-step explanation:
The radical expression that is equivalent to the expression (35)^1/4 is the fourth root of 35, which can be denoted as √435 or 351/4. In general, when we raise a number to a fractional power, the numerator of the fraction indicates the power and the denominator indicates the root. Hence, raising 35 to the 1/4 power is equivalent to taking the fourth root of 35. This operation involves finding a number which, when multiplied by itself four times, equals 35. While this cannot be simplified to an integer or simple fraction, it can be estimated using a calculator or left in radical form for exact representation.
