`a)`
`10 + 2x = 4^5 : 4^3`
`=> 10 + 2x = 4^2`
`=> 10 + 2x =16`
`=> 2x =16-10`
`=>2x=6`
`=>x=6:2`
`=>x=3`
`b)`
`155 - 10 (x+1)=55`
`=> 10 (x+1)=155 -55`
`=> 10 (x+1)=100`
`=>x=1=100:10`
`=>x+1=10`
`=>x=10-1`
`=>x=9`
`c)`
`14x + 54 = 82`
`=>14x= 82-54`
`=>14x= 28`
`=>x=28:14`
`=>x=2`
`d)`
`6(x+2^3)+40=100`
`=> 6(x+8)=100-40`
`=> 6(x+8)=60`
`=>x+8=60:6`
`=>x+8=10`
`=>x=10-8`
`=>x=2`
`e)`
`15x - 133 = 17`
`=>15x= 17 + 133`
`=>15x= 150`
`=>x=150:15`
`=>x=10`
`f)`
`2^2(x+3^2)-5=55`
`=>4 (x+9)=55+5`
`=> 4 (x+9)=60`
`=>x+9=60:4`
`=>x+9=15`
`=>x=15-9`
`=>x=6`
c đáp án cuối là 2 nha bạn, nãy mik làm nhầm, sorry
