20. $left(left(\frac{4}{5}\right)^{0}cdotleft(\frac{4}{5}\right)^{1}\right)^{2}$
20. $left(left(\frac{4}{5}\right)^{0}cdotleft(\frac{4}{5}\right)^{1}\right)^{2}$
Answer
Explanation:
Step1: Calculate exponents
Any non - zero number to the power of 0 is 1, so $(\frac{4}{5})^0 = 1$, and $(\frac{4}{5})^1=\frac{4}{5}$. Then $(\frac{4}{5})^0\cdot(\frac{4}{5})^1=1\times\frac{4}{5}=\frac{4}{5}$.
Step2: Square the result
$(\frac{4}{5})^2=\frac{4}{5}\times\frac{4}{5}=\frac{16}{25}$
Answer:
$\frac{16}{25}$
