How do I write as a radical expression
a^7/8
To write the expression "a^7/8" as a radical expression, we can use the properties of radicals.
Step 1: Recall that the nth root of a number is written as √n, where the symbol √ represents the radical.
Step 2: Start by identifying the denominator, which is 8. This implies we will be taking the 8th root.
Step 3: To determine the base, we consider the numerator, which is 7. This indicates that the base will be "a."
Therefore, combining the information from steps 2 and 3, we can express "a^7/8" as √8(a^7).
Alternatively, you can also express it in exponent form by using fractional exponents. The expression "a^7/8" is equivalent to (a^(1/8))^7, which can be written as (the 8th root of 'a')^7.
