Question

Evaluate the expressions.

Answer 1

Answer:

- 1 and 1

Step-by-step explanation:

using the rule of exponents

• $a^{0}$ = 1

- ($2^{0}$) = - 1

( - $\frac{4}{9}$)^0 = 1

Answer 2

For this case we have that by definition, any number raised to zero gives 1.

Knowing that:

$\frac {a ^ 2} {a ^ 2} = 1$ and by power properties of the same base we have that: $\frac {a ^ 2} {a ^ 2} = a ^ {2-2} = a ^ 0$

So:

$a ^ 0 = 1$

So, if we have:

$- (2) ^ 0 = - (1) = - 1\\(- \frac {4} {9}) ^ 0 = 1$

Answer:

$- (2) ^ 0 = - (1) = - 1\\(- \frac {4} {9}) ^ 0 = 1$
