Answer 2

\(A=\dfrac{\left(20.5\right)^5.5^5}{100^5}=\dfrac{100^5.3125}{100^5}=3125\)

\(B=\dfrac{\left(0,3.3\right)^5}{\left(0,3\right)^5.0,3}=\dfrac{\left(0,3\right)^5.3^5}{\left(0,3\right)^5.0,3}=\dfrac{3^5}{0,3}=810\)

Answer 3

\(A=\dfrac{2^{10}\cdot5^5\cdot5^{10}}{2^{10}\cdot5^{10}}=5^5=3125\\ B=\left(\dfrac{0,9}{0,3}\right)^5\cdot\dfrac{1}{0,3}=\dfrac{3^5}{0,3}=\dfrac{243}{0,3}=810\)

Answer 4

A=\(\dfrac{20}{20.5}\)=5¹⁰/5⁵=5⁵

B=(0,3)⁵x3⁵/(0,3)⁶=3⁵/0,3
