\(325\left(37+45\right)-63\left(-325\right)+45\left(-225\right)\)
\(=325\cdot37+325\cdot45+63\cdot325-45\cdot225\)
\(=325\left(37+63\right)+45\left(325-225\right)\\ =325\cdot100+45\cdot100\\ =100\left(325+45\right)\\ =100\cdot370\\ =37000\)
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
325x(37+45)-63x(-325)+45x(-225)
=325x(82)-63x(-325)+45x(-225)
=26650-(-20475)+(-10125)
=47125+(-10125)
=37000
chúc bạn học tốt
a) \(-75+\left(-325\right)+\left|-45\right|-\left(-125\right)\)
\(=-75-325+45+125\)
\(=\left(45+125\right)-\left(75+325\right)\)
\(=170-400\)
\(=-230\)
b) \(62+\left|128\right|-\left|-155\right|-\left|70\right|\)
\(=62+128-155-70\)
\(\Leftrightarrow190-225\)
\(=-35\)
c) \(815+\left[95+\left(-815\right)+\left(-45\right)\right]\)
\(=815+95-815-45\)
\(=\left(815-815\right)+\left(95-45\right)\)
\(=0+50\)
\(=50\)
d) \(5+\left(-7\right)+9+\left(-11\right)+...+25+\left(-27\right)\)
\(=\left(5-7\right)+\left(9-11\right)+...+\left(25-27\right)\)
\(=-2-2-...-2\)
\(=-2.11\)
\(=-22\)
e) \(34+35+36+37-24-25-26-27\)
\(=\left(34-24\right)+\left(35-25\right)+\left(36-26\right)+\left(37-27\right)\)
\(=10+10+10+10\)
\(=40\)
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
b)\(\dfrac{45^2.40^2.18^2}{180^2}=\dfrac{45^2.4.10.4.10.18.18}{180^2}=\dfrac{45^2.4.4.180.180}{180^{20}}=\dfrac{45^2.16}{ }\)
bạn nhầm đề rồi
