Question

How do you simplify this radical expression?

Answer 1

\[\sqrt{(a-b)}^{2}\]

Answer 2

a-b?

Answer 3

Thats what I was thinking. But is it that?

Answer 4

it sounds too simple but I dont see anything else ..

Answer 5

Yeah exactly what I was thinking. I dont see another solution here... So it probably is that.

Answer 6

because it is too simple and also wrong

Answer 7

\[\sqrt{x^2}=|x|\]

Answer 8

so
\[\sqrt{(a-b)^2}=|a-b|\]

Answer 9

for example
\[\sqrt{(3-5)^2}\neq 3-5\] it is
\[|3-5|=2\]

Answer 10

Ok so it would be ab?

Answer 11

no not
\[ab\] that means
\[a\times b\]

Answer 12

it is
\[|a-b|\] the absolute value of
\[a-b\]

Answer 13

yeah sorry that is right ^^"

Answer 14

OK I see. Thanks. :)
