cậu nên tách ra nhé!
Bài `1`
`7.7.7=7^3 `
`x.x.y.y .x.y.x=x^4 .y^3`
`7.35.7 .5.5=35.35.35=35^3`
`2.3.8.12.24=2.3.2.2.2.3.2.2.3.2.2.2 = 2^9 . 3^3`
Bài `2`
`3^5 . 3^2=3^(5+2)=3^7`
`8^7 : 8^5 =8^(7-5)=8^2`
`a^5 . a^3 : a^2=a^(5+3-2)=a^6`
`4^2 . 4^7 .2 =4^(2+7+1)=4^(10)`
`6^9 : 6^3 :6=6^(9-3-1)=6^5`
`m^6 : m^2 . m^3=m^(6-2+3)=m^7`
`x^5 . x^6 . x=x^(5+6+1)=x^(12)`
`y^(10):y^5 :y^2=y^(10-5-2)=y^3`
`x^2. x^7 : x=x^(2+7-1)=x^8`
bài 1
a)7^3
b)7^2.35.5^2
c)x^4.y^3
còn mấy bài khác mik chịu nha sorry
Bài 1:
