Question

i dont remember what the 0 means for example -(2a)^0

Answer 1

\[b^0=1\] but be careful because in your example
\[-(2a)^0=-1\]

Answer 2

Any number raised to the zero power is 1. So the answer is -1.

Answer 3

the exponent is 0

Answer 4

the old "order of operations"

Answer 5

PEMDAS FTW

Answer 6

so for example
\[7^0=1\] but
\[-7^0=-1\] and
\[2\times 7^0=2\times 1=2\] etc

Answer 7

caution: if a = 0, then the expression would not evaluate to 1

Answer 8

okay thanks. :-)

Answer 9

or -1 in your case :-P

Answer 10

it is true that
\[0^0\] is not a number, although there seems to be some controversy about it

Answer 11

yet it approaches 1

Answer 12

so it could be handy to define 0^0 as equal to 1 if it makes things easier for whatever you're trying to do.

Answer 13

well.. it doesn't really approach 1 from the left... :-(
