a) 28 * x + 72 * x = 80 * 125
(28 + 72) * x = 10000
100 * x = 10000
x = 100
b) x - 625 : 25 * 5 = 200
x - 125 = 200
x = 200 + 125
x = 325

(2x+3)2 = (3/11)2
2x+3 = 3/11
2x = 3/11 - 3
2x = -30/11
x = -60/11

\(\dfrac{2^{15}\cdot9^4}{6^6\cdot8^3}=\dfrac{2^{15}\cdot\left(3^2\right)^4}{\left(3\cdot2\right)^6\cdot\left(2^3\right)^3}=\dfrac{2^{15}\cdot3^8}{3^6\cdot2^6\cdot2^9}=\dfrac{2^6\cdot3^2}{2^6}=3^2=9\)
