\(325\left(37+45\right)-63\left(-325\right)+45\left(-225\right)\)
\(=325\cdot37+325\cdot45+63\cdot325-45\cdot225\)
\(=325\left(37+63\right)+45\left(325-225\right)\\ =325\cdot100+45\cdot100\\ =100\left(325+45\right)\\ =100\cdot370\\ =37000\)
325.(37+45)-63.(-325)+45.(-225)
=325.37+325.45+63.325+45.(-225)
=325.(37+63)+45.(325-225)
=325.100+45.100
=100.(325+45)
=100.370
=37000
mình chắc là nó đúng
454x404x182/1806
=454x404x182/186x106
=454x404/184x106
=454x104x44/184x106
=454x44/184x102
=154x34x22x22/64x34x52x22
=154x1x1x22/64x1x52x1
=154x22/64x52
=54x34x22/34x24x52
=52x1x1/1x22x1
=52/22=25/4
453 = (9.5)3 = 36.53
204 = (4.5)4 = 28.54
182 = (9.2)2 = 34.22
1805 = (4.9.5)5 = 210.310.55
\(=\dfrac{3^6.5^3.2^8.5^4.3^4.2^2}{2^{10}.3^{10}.5^5}=\dfrac{2^{10}.3^{10}.5^7}{2^{10}.3^{10}.5^5}=5^2=25\)
\(B=\dfrac{11.3^{29}-3^{30}}{4.3^{28}}=\dfrac{3^{29}\left(11-3\right)}{3^{28}.4}=\dfrac{3.8}{4}=6\)
Ta có: \(E=\frac{45^2.20^4.18^2}{180^3}\)
=> \(E=\frac{\left(3^2.5\right)^2.\left(2^2.5\right)^4.\left(3^2.2\right)^2}{\left(2^2.3^2.5\right)^3}\)
=> E = \(\frac{3^4.5^2.2^8.5^4.3^4.2^2}{2^6.3^6.5^3}\)
=> E = \(\frac{3^8.5^6.2^{10}}{2^6.3^6.5^3}\)
=> E = \(3^2.5^3.2^4=18000\)
= \(\frac{45^2.4^4.5^49^2.2^2}{45^2.5.9.4^3}=4.5^3.9.2^2=18000\)
em zì ơi t.i.c.k a với nhé
325x(37+45)-63x(-325)+45x(-225)
=325x(82)-63x(-325)+45x(-225)
=26650-(-20475)+(-10125)
=47125+(-10125)
=37000
chúc bạn học tốt

H= 45^3.20^4.18^2/ 180^5 = (3^2.5)^3.(2^2.5)^4.(2.3^2)^2/ (2^2.3^2.5)^5 = 3^6.5^3.2^8.5^4.2^2.3^4/ 2^10.3^10.5^5 = 3^10.5^7.2^10/ 2^10.3^10.5^5 = 5^2=25

bạn nhầm đề rồi
