Isent this a negative number?

Question

(1-(1/(1+A3)^A2))/A3 Isent this a negative number, please explain and hold the scarcasim!

Answer 1

It's only negative if 1/(1+A3)^A2) is greater than one or A3 is negative and (1-(1/(1+A3)^A2)) is positive.

Answer 2

Both C C and primrosh have answered the original question which contains A1, A2, and A3.

Here is your revised expression:

(1-(1/(1+.1)^35))/.1 .......[Simplify the inner parentheses (1 + .1) = 1.1]

(1-(1/(1.1)^35))/.1 .........[Simplify (1.1)^35 = 28.1 but it doesn't really matter because what's important is that this is greater than 1.]

(1-(1/(28.1))/.1 .............[Simplify 1/28.1 = .035]

(1-.035)/.1

(.126)/.1

1.26

Your revised expression is equal to 1.26 so it will always be positive.

Answer 3

No! Not necessarily.

It depends on the value of A.

The value of A can be positive or negative; less than one, equal to one or greater then one.

All the different values of A will give you a different result.
