But what is 0^0?
Is it 1 or is it 0?MGMAT book
"By definition, any base raised to 0 power yields 1"
"Any exponent expression with a base of 0 always yields 0, regardless of exponent"
I know this may be simple for some, but I never learned this.
Thanks for your help
No, it's not simple even for mathematicians. There's debate about how 0^0 should be defined; some think it should be defined to be equal to 1, but normally it's considered to be undefined (because, if you know calculus, limit(x -> 0) x^0 = 1, while limit(x -> 0) 0^x = 0).
So the MGMAT book
is incorrect, if you've quoted it accurately- they should leave out the case of 0^0. Not that it matters on the GMAT- you'll never encounter this exceptional case on the test.
