Question

Ajutor va rog!
Ofer coronița!!!!

Answer 1

Răspuns:

1)

$(5 - 3) \times {5}^{x} = 2 \\ 2 \times {5}^{x} = 2 \\ {5}^{x} = 1 \\ {5}^{x} = {5}^{0} \\ x = 0$

2)

$125 \div 125 = \frac{1}{5} + 125 \\ x = \frac{1}{5} \times \frac{1}{25} \\ x = \frac{1}{625}$

3)

$(1 + {2}^{3} ) + \times {2}^{x} = 36 \\ (1 + 8) \times {2}^{x} = 36 \\ 9 \times {2}^{x} = 36 \\ {2}^{x} = 4 \\ {2}^{x} = {2}^{2} \\ x = 2$

succes❗
