66x66=4356
k mk nhé,1000000% đúng
a. 11 x11= 121 ; 22 x 22=484 , b.44 x 44 = 1936 ; 55 x 55 = 3025
\(5^5.\dfrac{1}{20}.2^2.3^3:125\)
\(=5^5.\dfrac{1}{2^2.5}.2^2.3^3:5^3\)
\(=\dfrac{2^2.3^3.5^5}{2^2.5^4}=3^3.5=27.5=135\)
= 3125 x 1/20 x 4 x 27 : 125
= 625/4 x 4 x 27 : 125
= 625 x 27 : 125
= 16875 : 125
= 135
33x55x(22x3-66)
=33x55x(66-66)
=55x55x0
=0
thấy đúng thì tích nha
\(\frac{7}{9}\cdot\frac{3}{5}=\frac{7\cdot3}{9\cdot5}=\frac{7\cdot1}{3\cdot5}=\frac{7}{15}\)
\(\frac{9}{22}\cdot55=\frac{9}{22}\cdot\frac{55}{1}=\frac{9\cdot55}{22\cdot1}=\frac{9\cdot5}{2\cdot1}=\frac{45}{2}\)
\(\frac{11}{17}:\frac{33}{34}=\frac{11}{17}\cdot\frac{34}{33}=\frac{11\cdot34}{17\cdot33}=\frac{1\cdot2}{1\cdot3}=\frac{2}{3}\)
(45+75)*66+(75+45)*34
=(45+75)*(66+34)
=120*100
=12000
11+22+33+44+55+66+77+88+99:11
=11+22+33+44+55+66+77+88+9
=(11+9)+(22+88)+(33+77)+(44+66)+55
=20+110*3+55
=20+330+55
=405
Ta có :
a, (45 + 75) x 66 + (75 + 45) x 34
= (45 + 75) x (66 + 34)
= 120 x 100
= 12000
11 + 22 + 33 + 44 + 55 + 66 + 77 + 88 + 99 : 11
= 33 + 77 + 121 + 165 + 9
= 405
X + 6 = 33
X = 33 − 6
X = 27
9 + x = 22
X = 22 − 9
X = 13
X − 41 = 41
X = 41 + 41
X = 82
Câu 2:
\(\dfrac{7}{9}\cdot\dfrac{3}{35}=\dfrac{1}{5}\cdot\dfrac{1}{3}=\dfrac{1}{15}\)
\(\dfrac{9}{22}\cdot55=\dfrac{9\cdot55}{22}=\dfrac{9\cdot5}{2}=\dfrac{45}{2}\)
