Answer 1

Răspuns:

b) 625-x= 576

x= 625- 576

x= 49

x=7 la puterea 2

a) x la puterea 2÷2 la puterea 2= 3 la puterea 2

x la puterea 2 ÷4= 9

x la puterea 2= 9×4

x la puterea 2= 36

x= 6 la puterea 2

c) x ÷ 10 la puterea 3= 10 la puterea 0

x÷ 1000= 1

x= 1000×1

x = 1000 ( sau cu 10 la puterea 3)

d) 441 ÷x= 21 la puterea 2

441÷x= 441

x= 1

e) x- 2 la puterea 5 = 5 la puterea 3

x- 32 = 125

x = 125 +32

x = 157
