Understand the expression: Understand the expression 30(1/4).The expression 30(1/4) means the fourth root of 30. The fourth root of a number is the number that, when raised to the power of 4, gives the original number.
Determine perfect fourth power: Determine if 30 can be expressed as a power of a number that is a perfect fourth power.30 is not a perfect fourth power, and it cannot be expressed as a power of a number that is a perfect fourth power. However, we can look for factors of 30 that are perfect fourth powers to simplify the expression.
Factor into prime factors: Factor 30 into its prime factors.30=2×3×5None of these prime factors are perfect fourth powers, so we cannot simplify the expression by extracting a perfect fourth power from under the radical.
Express in simplest form: Express 301/4 in simplest radical form.Since we cannot simplify 30 by extracting a perfect fourth power, the simplest radical form of 301/4 is the fourth root of 30, which is written as 430 with a small 4 on the radical symbol to indicate the fourth root.
