$\sqrt{x-2} \cdot \sqrt{x-5} = (x-2)^\frac{1}{2} \cdot (x-5)^\frac{1}{2}$
$a^{b} \cdot b^{a} = ab^{a+b}$
$(x-2)^\frac{1}{2} \cdot (x-5)^\frac{1}{2}$
$(x^2-7x-10)^\frac{1}{2} + ^\frac{1}{2}$

What do you call "a proper way" ? Something like $\frac{a}{b}+\frac{c}{d}=42$ ? (click on the formula to see the code I typed)

Yes i know, but i want to add two fractions as raised to the power of X

$\left( \frac{x-2}{8} \right)^2 \cdot \left( \frac{x-5}{8} \right)^2= \frac{(x-2)^2(x-5)^2}{8^4}$ ? Let me know if it is -still- not what you meant.

Hi,

No, i want to add 1/2 + 1/2 in raised form. Like X^1/2 + 1/2

OK, I think I've understood : $x^{\frac{1}{2}+\frac{1}{2}}$

Yes, thank you

Also useful maybe : $\sqrt[4]{x^3}=x^{\frac{3}{4}}$ .

testing $\alpha\beta\frac{2x^2-4}{\sqrt{a^2-bx^2}}$
