Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
Another good one
Think it is C)
From A) X=1, Y=1 or X=5,Y=0 then stem may be or may not be 0
B) by itself is not suff-all three may be 0 or any other integer
From both when X=Y=Z=1 we get ans to question
Another comment: Please don't ask me to "define" 00. There are at least two ways of looking at this quantity:
* Anything to the zero power is "1", so 0^0 = 1.
* Zero to any power is zero, so 0^0 = 0.
As far as I know, the "math gods" have not yet settled on a "definition" of 00. In fact, in calculus, "00" will be called an "indeterminant form". If this quantity comes up on class, don't assume: ask your instructor what you should do with it.
I would go w/ E as it's not clear what's the value of 0^0.
I maintain my point of view It's a result very specific and famous for it
To the ones that doubt, i suggest that they use the window calculator for example. They can calculate 0^0=1.... The result is 1
And to be sure, they can try: > -1,2^2,1 >>>> Invalid input function > 1/0 >>>> cannot divid by zero
In addition, this result is required for a "Serie" representing a fonction. For the ones who remind it, we have f(x)= Sigma( a(k)*x^k ) where k start from 0 and tend to infinate.
We can imagine imagine a fonction defined for a the value of x=0 thus f(0) = a(0)*0^0 = a(0)
Don't be confused. Windows calculator is not a maths standard. Windows did not design calculator to clarify the math fundamentals. See the below link. It is clearly stated that "A number other than 0 taken to the power 0 is defined to be 1" http://mathworld.wolfram.com/Power.html
NOTE: This is one of the trusted link. _________________
Interesting link The content does not state on 0^0.
Moreover, concerning calculators, I have tried on 3 differents, one of them is my old HP 48S confirmed it ... Excell works on it too... and so on Windows calculator is just a common and easy-to-access calculator
I personnaly practiced, well a few time ago, some math problems involving 0^0. As i said, a 'serie' represating a fonction is one application.
