What is 7^0?

Question

Isn't anything to the 0 power equal to 1? Can someone explain why?

Answer 1

You are correct; anything to the power of 0 does equal 1.

Here is a link that explains why:

Answer 2

X^0 = 1

Answer 3

Anything to the power of 0 is 1.

Answer 4

Quotients of x^n / x^m can be depicted as x^(n - m); An extension of x^0 can be written as x^(n - n), which is also x^n / x^n. Note the numerator and the denominator is the same value, therefore when x^0, x ≠ 0, the quotient value will indeed be 1 (a number divided by itself is 1 if the number is not 0).

Answer 5

yes any number except for 0 raised tothe zero power is 1

If you have an exponent fraction that looks like this

5^2 25
---- =---------=1
5^2 25

5^2/5^2= 5^2-2=5^0=1

1=5^2/5^2=5^2-5^2=5^0=1

Answer 6

a^0 = 1
If you take logs of both sides, you get
log(a^0) = log(1)
0*log(a) = log(1)

Since the LSH = 0, we need the RHS = 0, hence it must be log(1).
