How can I replace an inline function with a anonymous function?

Usually when I used to work with inline functions I was able to call the formula from a variable. For example:

a=input('Insert a number: ');
formulaOne=['x.^',num2str(a)]; 

Example=inline(formulaOne,'x');
disp(feval(Example,10))

And the result was equal to 10^a. This is an example but I have a code that generates different formulas so I want to replace the inline function with an @() function.

Here's what I tried:

a=input('Insert a number: ');
formulaOne=['x.^',num2str(a)];

Example=@(x) formulaOne;
disp(Example(10))

I wanted to get the numerical value of the function but I get the text instead:

x.^2 %this is the result I'm getting.

So can I make it read the formula from formulaOne and evaluate it with an anonymous function instead of getting the formula itself?.

Pd. I don't have the Symbolic Math Toolbox instaled so I can't use syms or matlabFunction to solve it.

a=input('Insert a number: ');
Example=@(x) x.^a;
disp(Example(10))

Alternatively, you can use str2func to create a function handle from a char array.
