\(\dfrac{8^{10}.15^{16}}{12^{15}.25^8}\)
=\(\dfrac{\left(2^3\right)^{10}.\left(3.5\right)^{16}}{\left(2^2.3\right)^{15}.\left(5^2\right)^8}\)\(\)
=\(\dfrac{2^{30}.3^{16}.5^{16}}{^{ }2^{30}.3^{15}.5^{16}}\)
=\(\dfrac{1.3.1}{1.1.1}\)
= \(3\)

x = 0

\(-\dfrac{2 }{3}.\dfrac{9}{7}+\dfrac{3}{4}:2,5 \)
= \(-\dfrac{6}{7}+\dfrac{3}{10}\)
= \(-\dfrac{39}{70}\)
