Question

a)X-2pa puterea 2 = 3 la puterea 3 B) 100-X=4 la puterea 2 c( X+3 la puterea 2 + 3 =4 la puterea 0. D)(x+1)•2 la puterea 2 =12

Answer 1

Explicație pas cu pas:

a)

x - 2² = 3³

x - 4 = 27

x = 27 + 4 => x = 31

b)

100 - x = 4²

100 - x = 16

x = 100 - 16 => x = 84

c)

x + 3² + 3 = 4⁰

x + 9 + 3 = 1

x + 12 = 1

x = 1 - 12 => x = -11

d)

(x+1)•2² = 12

(x+1)•4 = 12

x + 1 = 12:4

x + 1 = 3

x = 3 - 1 => x = 2
