factor x^-1/2 + x^5/2

the -1/2 and 5/2 are powers

i dont see how anything comes out?

To

. . . . .x^(-1/2) + x^(5/2)

You can also use the "sup" tags (from the formatting line above the message-entry box):

. . . . .x

...displays as:

. . . . .x

Nothing much does, actually...

Use

. . . . .

You might find it easy, by the way, to convert the fractional powers to radical form, while you're doing your steps:

. . . . .

. . . . .

The common denominator is the square root of x, but of course you're not supposed to have radicals in the denominator, so let's "rationalize" that first:

. . . . .

. . . . .

Now the common denominator would be x, so:

. . . . .

. . . . .

The only common factor is the radical:

. . . . .

so its (square root of x)(1+x)(1+x+x^2)/x?
