Use the rational exponent property to write an equivalent expression for square root 5 n^4 +3 - 12

Using the rational exponent property, we can write the expression as:

(sqrt(5n^4))^2 + 3 - 12

Simplifying further, we have:

5n^4 + 3 - 12

Therefore, an equivalent expression for sqrt(5n^4) + 3 - 12 using the rational exponent property is 5n^4 + 3 - 12.
