Question

Simplify 17√17-9√17

Answer 1

8
8√7
26√17
8√0

Answer 2

to make this question easier, let's say
let x = √17

So from 17√17 - 9√17,
we have 17x - 9x = ?

Answer 3

Treat it as a normal subtraction in algebra :)

Answer 4

note that root17 is common
you can factor it

Answer 5

all you gonna be doing is 17-9=?

Answer 6

so 17-9=8

Answer 7

substitute 8 for both 17?

Answer 8

well... we said let x = √17 right?
So we changed our equation from 17√17 - 9√17 TO 17x - 9x = 8x

Now, we know that 17x - 9x = 8x, where x = √17

Therefore 17√17 - 9√17 = 8√17

Answer 9
