What is the value of 2 over 3 to the power of 0 to the power of -3

Schach [20]

Answer:

$((\frac{2}{3})^0)^{-3}=1$

Step-by-step explanation:

We need to find the value of $((\frac{2}{3})^0)^{-3}$

Solving:

We know, $(a^b)^n = a^{b*n}$

$((\frac{2}{3})^{0*-3})$

$(\frac{2}{3})^0$

a^0 = 1

so,

$(\frac{2}{3})^0=1$

So, the value of $((\frac{2}{3})^0)^{-3}=1$
