Question

bn ơi giúp mình nhé
3^4 . 2^2 + 2^3 ( x - 25 ) = 604

ai là trả lời đúng là mình sẽ tick hết luôn

Answer 1

\(3^4.2^2+2^3.\left(x-25\right)=604\)

\(\Rightarrow81.4+8.\left(x-25\right)=604\)

\(\Rightarrow8.\left(x-25\right)=604-81.4\)

\(\Rightarrow8\left(x-25\right)=604-324\)

\(\Rightarrow8\left(x-25\right)=280\)

\(\Rightarrow x-25=280:8\)

\(\Rightarrow x-25=35\)

\(\Rightarrow x=35+25\)

\(\Rightarrow x=60\)

Answer 2

\(3^4.2^2+2^3\left(x-25\right)=604\)

\(324+2^3\left(x-25\right)=604\)

\(2^3\left(x-25\right)=604-324\)

\(2^3\left(x-25\right)=280\)

\(\left(x-25\right)=280:2^3\)

\(\left(x-25\right)=35\)

\(x=35+25\)

\(x=60\)

Answer 3

3^4.2^2+2^3(x-25)=604

81.4+8(x-25)=604

324+8(x-25)=604

8(x-25)=604-324

8(x-25)=280

x-25=280:8

x-25=35

x=35+25

x=60 

Vậy x=60

Answer 4

3⁴ . 2² + 2³ . ( x - 25 ) = 604

81 . 4 + 8 . ( x - 25 ) = 604

324 + 8 . ( x - 25 )    = 604

         8 . ( x - 25 )    = 604 - 324

         8 . ( x - 25 )    = 280

                x - 25      = 280 : 8

                x - 25      = 35

                x            = 35 + 25

                x            = 60

Answer 5

\(3^4\cdot2^2+2^3.\left(x-25\right)=604\)

\(81\cdot4+8.\left(x-25\right)=604\)

\(324+8.\left(x-25\right)=604\)

\(8.\left(x-25\right)=604-324\)

\(8.\left(x-25\right)=280\)

\(x-25=280:8\)

\(x-25=35\)

\(x=35+25\)

\(x=60\)

Answer 6

3⁴ .2² +2³ (x-25)=604

81.4+8(x-25)=604

324+8(x-25)=604

8(x-25)=604-324

8(x-25)=280

x-25=280:8

x-25=35

x=60
