suy ra: (x +35) =515 :5

 suy ra;    x +35=103

 suy ra:           x=103-35

suy ra:              Vậy x=68

đúng nha!!!!!! 100% lun!!!!!!!! !!!!!!!!!!

5(x+35) = 515

x + 35 = 515 : 5

x + 35 = 103

       x  = 103 - 35

       x  = 68

a) x = 2

b) x = 8

c) x = 1 hoặc x = 0

a) 2⁴ = x⁴
\(\Rightarrow\)x = 2
b) 3^x = 3⁸
\(\Rightarrow\)x = 8
c) x⁴⁰ = x
\(\Rightarrow\orbr{\begin{cases}x=1\\x=0\end{cases}}\)

3x - 7 = 2^2 . 3^2

3x - 7 = 36

3x = 36 + 7 

3x = 43

x = 43 : 3

x = 43/3

3x - 7 = 2² . 3²

3x - 7 = 4 . 9

3x - 7 = 36

3x = 36 + 7

3x = 43

  x = 43 : 3

  x = \(\frac{43}{3}\)

\(2^{10}\)có 4 chữ số
