## anonymous 4 years ago (-9x^2y^3)^0=1? is the answer 1 because anything raised to the 0 power is 1?

1. anonymous

Aye

2. Hero

yup

3. anonymous

ok great

4. TuringTest

not true if x or y are zero!

5. anonymous

what do you mean, like if it is -9x^0?

6. TuringTest

no, I mean$0^0\neq1$and the expression becomes zero to the zero if x and/or y are zero

7. TuringTest

$a^0=1\text{ for all }a\neq0$because$0^0$is undefined (has no specific meaning)
