9 to the 5 over 2 in the simplest radical form will be 243 or 9 to the root 3.
<u>Explanation</u>
- Simplest radical form in mathematics re those expressions in which there re no roots, sure roots, cube roots or fourth root to be solved. According to the Merriam Webster dictionary, the word radical means or relating to or originating from the root. It also means going to the root or foundation of any specific thing.
- The use of the simplest radical form is to get rid-off roots to be it sure root, cube root or fourth root in n expression. In the end there are no radicals in the denominator part of the fraction if we are dealing with fractions.
- In the given problem 9 to the 5 over 2 in the simplest radical form will be 243 will be further deduced to 9 to the root 3.
- The following steps would make the problem more simple:
9 to the 5 over 2
=(3^2)^5/2
=3^5
=243
or,
9 to the root 3
