To express in radical form, follow these steps:
1.Understand the Exponent Fraction:
The exponent indicates that you first take the cube root (since the denominator is 3) and then square the result (since the numerator is 2).
2.Apply the Formula:
The formula for converting an exponent of the form into radical form is .
Here, ( a = 7z ), ( m = 2 ), and ( n = 3 ).
So,
