Question

460+85.4=( x +200) ÷ 4

5^x=125

Answer 1

5^x = 125

x = 3

460 + 340 = (x + 200) : 4

800 = (x + 200) : 4

x + 200 = 800 : 4

x + 200 = 200

x = 200 - 200

x = 0

Answer 2

460 + 340 = (x+200):4

8--=(x+200):4

x+200=800:4

x+200=200

x=200-200

x=0

5^x=125

x=3

Answer 3

\(460+85.4=\left(x+200\right):4\)

\(\Rightarrow\left(x+200\right):4=460+85.4\)

\(\Rightarrow\left(x+200\right):4=460+340\)

\(\Rightarrow\left(x+200\right):4=800\)

\(\Rightarrow\left(x+200\right)=800.4\)

\(\Rightarrow x+200=3200\)

                  \(x=3200-200\)

                    \(x=3000\)

          Vậy \(x=3000\)

b) \(5^x=125\)

\(\Rightarrow5^x=5^3\)

Cơ số giống nhau suy ra số mũ giống nhau 

\(\Rightarrow x=3\)

Vậy \(x=3\)

Answer 4

460+340=(x+200)÷4

800=(x+200)÷4

x+200=800×4

x+200=3200

x=3200-200

x=3000

5^x=125

5^x=5^3

x=3

Answer 5

460 + 85.4= ( x + 200 ) : 4 

460 + 340 = ( x + 200 ) : 4 

800 = ( x + 200 ) : 4 

x + 200 = 800 . 4 

x + 200 = 3200 

x = 3000 

Answer 6

1/ 460 + 85.4 = ( x + 200 ) : 4

    460  + 340 = ( x + 200 ) : 4

    800 = ( x + 200 ) : 4

    800 . 4 = x + 200

    3200 = x + 200

    3200 - 200 = x

    3000 = x

2/ 5^x = 125

    5^x = 5³

=> x = 3

Answer 7

460+85.4=(x+200):4

460+340=(x+200):4

800=(x+200):4

3200=(x+200)

x=3000

5^x=125

5^x=5³

Suy ra:x=3

Answer 8

\(460+85.4=\left(x+200\right):2\)

\(460+340=\left(x+200\right):4\)

\(800=\left(x+200\right):4\)

\(\left(x+200\right):4=800\)

\(x+200=800.4\)

\(x+200=3200\)

\(x=3200-200\)

\(x=3000\)

\(5^x=125\)

\(5^x=5^3\)

Vì \(5=5\)

\(\Rightarrow x=3\)
