`a, 35 1/6 *(-4/5)-45 1/6*(-4/5) `
`= (-4/5)*(35 1/6 - 45 1/6)`
`= (-4/5)* -10 = -8`
`b, 9/23-7/40+14/23+1,7-33/40`
`= (9/23+14/23)+(-7/40-33/40)+1,7`
`= 1+(-1)+1,7=0+1,7=1,7`
`c, 3- (-6/7)^0+(1/2)^2 \div 2`
`= 3-1+1/4 \div 2`
`= 3-1+1/8`
`= 2+1/8=17/8`
`d,` Cậu chụp lại hoặc ghi đầy đủ đề giúp mk với ạ!
`e, ((3)^2)^2-((-5)^2)^2+((-2)^3)^2`
`= (9)^2-(25)^2+(-8)^2`
`= 81-625+64=-544+64=-480`
`f, 3 \div (-3/2)^2+1/9 *`\(\sqrt{36}\)
`= 3 \div 9/4+1/9*6`
`= 4/3+2/3=2`
a: =-4/5(35+1/6-45-1/6)
=-10*(-4/5)=8
b: =9/23+14/23-7/40-33/40+1,7=1,7
c: =3-1+1/4:2
=2+1/8
=17/8
d: =-8+4+1+1=-4+2=-2
f: =3:9/4+1/9*6
=4/3+2/3=2
