Answer :
[tex]23)\\\\-\sqrt{\frac{1}{121}}=-\frac{\sqrt{1}}{\sqrt{121}}=-\frac{1}{11}[/tex]
- √ (1/121)
You can break up the square root of a fraction like this: √(1/121) = √1 / √121 .
At this point, it helps if you know that 121=11x11, or √121 = 11.
So, the original expression is
- ( √1 / √121 ) = - ( 1 / 11 ) and there you are.
