+33+11
11*11=4
22*22=16
33*33=?
11+11=4
22=22=8
33=33=?
12 : Ghi sai dấu kìa :))
tính
11 + 11
22 + 22
33 + 33
11 + 11 = 22
22 + 22 = 44
33 + 33 = 66
11+11=11.2=22
22+22=22.2=44
33+33=33.3=66
B=11/13×40/13+37/5÷7/33-(11/13+33/7÷5/2)
Ta có: \(B=\dfrac{11}{13}\cdot\dfrac{40}{13}+\dfrac{37}{5}:\dfrac{7}{33}-\left(\dfrac{11}{13}+\dfrac{33}{7}:\dfrac{5}{2}\right)\)
\(=\dfrac{440}{169}+\dfrac{37}{5}\cdot\dfrac{33}{7}-\dfrac{11}{13}-\dfrac{33}{7}\cdot\dfrac{2}{5}\)
\(=\dfrac{297}{169}+\dfrac{33}{7}\cdot\left(\dfrac{37}{5}-\dfrac{2}{5}\right)\)
\(=\dfrac{297}{169}+\dfrac{33}{7}\cdot7\)
\(=\dfrac{297}{169}+33=\dfrac{5874}{169}\)
nếu 11+11=4
22+22=8
thì 33+33=?
Trước tiên là \(33+33=66\)đã.
\(\frac{33-33:\frac{11}{6}}{\frac{6}{11}}\)
\(\frac{33-33:\frac{11}{6}}{\frac{6}{11}}\)
\(=\frac{33-33\cdot\frac{6}{11}}{\frac{6}{11}}\)
\(=\frac{33-33\cdot1}{1}\)
\(=33-33=0\)
\(\frac{33-33:\frac{11}{6}}{\frac{6}{11}}\)
\(=\frac{33-33\cdot\frac{6}{11}}{\frac{6}{11}}\)
\(=\frac{33-18}{\frac{6}{11}}\)
\(=\frac{15}{\frac{6}{11}}\)
\(=\frac{55}{2}\)
* Bấm máy thấy sai xD Sửa lại tí *
\(\frac{33-33:\frac{11}{6}}{\frac{6}{11}}\)
\(=\frac{33-33\cdot\frac{6}{11}}{\frac{6}{11}}\)
\(=\frac{33-\frac{33\cdot6}{11}}{\frac{6}{11}}\)
\(=\frac{33-18}{\frac{6}{11}}\)\\(=\frac{15}{\frac{6}{11}}=\frac{15\cdot11}{6}=\frac{55}{2}\)

\(\frac{3}{4}=\frac{3\times5\times3}{4\times5\times3}=\frac{45}{60}\)
\(\frac{1}{5}=\frac{1\times4\times3}{5\times4\times3}=\frac{12}{60}\)
\(\frac{4}{3}=\frac{4\times5\times3}{3\times5\times4}=\frac{60}{60}=1\)
11 x 11 = 4
22 x 22 = 16
33 x 33 = ?
11x11=4
22x22=16
33x33=64 nha!
11 x 11 = 4
22 x 22 = 16
33 x 33 = 18
nha các bạn !!!
11 x 11 = 4
22 x 22 = 16
33 x 33 = ?
11*11=4 22*22=16 33*33=?
16 gấp 4 4 lần , suy ra 33*33 cũng gấp 16 4 lần
Vậy 33*33=64
