8 0

Answer:

Step-by-step explanation:

One way to solve the quadratic equation x2 = 9 is to subtract 9 from both sides to get one side equal to 0: x2 – 9 = 0. The expression on the left can be factored: (x + 3)(x – 3) = 0. Using the zero factor property, you know this means x + 3 = 0 or x – 3 = 0, so x = −3 or 3.

AVprozaik [17]

Answer:

There is no power of 4 that is equal to 0.

Step-by-step explanation:

$f(x) = log \: {4}^{x} \\ \\ plug \: x = 0 \\ \\ f(0) = log \: {4}^{0} \\ \\ f(0) = log \: 1 \: ( \because \: {n}^{0} = 1) \\ \\ f(0) = 0 \: ( \because \: log \: 1 = 0)$
