1)
[tex](5 - 3) \times {5}^{x} = 2 \\ 2 \times {5}^{x} = 2 \\ {5}^{x} = 1 \\ {5}^{x} = {5}^{0} \\ x = 0[/tex]
2)
[tex]125 \div 125 = \frac{1}{5} + 125 \\ x = \frac{1}{5} \times \frac{1}{25} \\ x = \frac{1}{625} [/tex]
3)
[tex](1 + {2}^{3} ) + \times {2}^{x} = 36 \\ (1 + 8) \times {2}^{x} = 36 \\ 9 \times {2}^{x} = 36 \\ {2}^{x} = 4 \\ {2}^{x} = {2}^{2} \\ x = 2[/tex]
succes❗
