To rewrite the cube root of 2 to the seventh power as a rational exponent, we need to understand the relationship between radicals and exponents. The cube root of a number can be expressed using a rational exponent as follows:
For any number a, the cube root can be written as a1/3. Therefore, the cube root of 2 can be written as:
21/3
Now, we want to find the cube root of 27. We apply the exponent to the radical:
(27)1/3
When we multiply the exponents, we get:
27/3
Thus, the cube root of 2 to the seventh power written as a rational exponent is 27/3.
