\(9+2+5+3+7+8+4+2+9+6+4+65+6+7+4+6+3+7+4+8+5+9+08+87+1+2+3+4+2+3+2+5+6+767+5+75+6+4+6+5+66+5+7+546+46+43+6+3+6+4+6+7+8878+68+68+6+7+9+9=10961\)
3 × 4 = 12 | 2 × 6 = 12 | 4 × 3 = 12 | 5 × 6 = 30 |
3 × 7 = 21 | 2 × 8 = 16 | 4 × 7 = 28 | 5 × 4 = 20 |
3 × 5 = 15 | 2 × 4 = 8 | 4 × 9 = 36 | 5 × 7 = 35 |
3 × 8 = 24 | 2 × 9 = 18 | 4 × 4 = 16 | 5 × 9 = 45 |
3: \(=20-12-8+12=20-8=12\)
5: \(=-18-42-21-35=-116\)
3: \(=-15+18-12+8=-27+26=-1\)
2: \(=-12+21-15+10=9-5=4\)
1: =1/8*9/4=9/32
2: =8/27*243/32=9/4
3: =(5/4*4/5)^5*(4/5)^2=16/25
4: \(=\left(-\dfrac{5}{6}\cdot\dfrac{6}{5}\right)^2\cdot\left(\dfrac{6}{5}\right)^2=\dfrac{36}{25}\)
5: \(=\left(-\dfrac{4}{3}\right)^3\cdot\left(\dfrac{3}{4}\right)^{10}=\left(-1\right)\left(\dfrac{3}{4}\right)^7=-\left(\dfrac{3}{4}\right)^7\)
6: \(=\left(\dfrac{1}{3}\cdot\dfrac{-9}{2}\right)^4\left(-\dfrac{9}{2}\right)^2=\left(-\dfrac{3}{2}\right)^4\cdot\dfrac{81}{4}=\dfrac{9}{4}\cdot\dfrac{81}{4}=\dfrac{729}{16}\)
8: =(0,2*5)^4*5^2=25
10: =-0,5^5*2^10
=-0,5^5*2^5*2^5
=-32
13: =(0,5*2)^2*2^2=4
\(\frac{\left(7^2.\frac{3}{5}-\left(3,5\right)^6+3^9.\frac{3}{5}\right)}{7^2.\frac{3}{4}-5^7.\frac{3}{4}+3^9.\frac{3}{4}}\) đề của bn đó là vậy á
