Question

Ex 6 si 7 Va rog urgent dau Coroana !!!!​

Answer 1

6. ai facut bine la a dar mai merge continuat 2⁵(1+32) = 2⁵* 33

b) 5⁴(1*3 + 5*2) = 5⁴(3+10) = 5⁴ * 13

c) a³(1+a²+a⁴)

d) x³y³(y+x -1)

e) 36ab(6a -b+1)

7. a) x: 3⁶ = 9

x : 3⁶ = 3²

x = 3² * 3⁶

x = 3⁸ = 6561

b) x + 7¹⁰ = 7¹⁰

x = 7¹⁰ - 7¹⁰

x = 0

c) 5⁴ˣ = 5²ˣ⁺⁴ avem aceeasi baza deci doar vom egala exponentii

4x = 2x+4

4x-2x = 4

2x = 4

x = 2
