1) Determine o conju exponenciais: a) 2X = 8 b) 2X = 64 c) 25x = 125 d) 7X = 343​

Explications étape par étape:

a. 2x = 8

[tex]x = \frac{8}{2} [/tex]

x = 4

b.2x = 64

[tex]x = \frac{64}{2} [/tex]

x = 32

c. 25x = 125

[tex]x = \frac{125}{25} [/tex]

x = 5

d. 7x =343

[tex]x = \frac{343}{7} [/tex]

x = 49
