What is an Expression?
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Using the different exponential properties, the value of the expression [tex]x^{\frac34}[/tex] can be written as,
[tex]x^{\frac34}[/tex]
Using the exponential property, [tex]x^{ab} = (x^a)^b[/tex],
[tex]= (x^3)^{\frac14}[/tex]
Using the exponential property, [tex]x^{\frac1b} = \sqrt[b]x[/tex],
[tex]= \sqrt[4]{(x^3)}\\\\= \sqrt[4]{x^3}[/tex]
Hence, the correct option is A.
