Answer 1

Răspuns:

a) ⁵⁰⁾5x/2+¹⁰⁰⁾3=1075/100

250x+300=1075

250x=1075-300

x=775:250=>x=31

b) 3x=1,11+2,7

x=3,81:3=>x=1,27

c) (25x/100)⁽²⁵=3/2-1

x/4=²⁾3/2-⁴⁾1

x=6-4=>x=2

d) x/9=(525/100)⁽²⁵+3

⁴⁾x/9=⁹⁾21/4+³⁶⁾3

4x=189+108

x=297/4=>x=74,25

e) 2x/9=3,75-3,5

2x/9=0,25

2x=0,25·9

x=2,25:2=>x=1,125

f) ³⁾2x/3=3/9+⁹⁾2

6x=3+18

x=21/6=>x=3,5

0,(3)=3/9=1/3

g) 5x/3+11/9=7/3

³⁾5x/3=³⁾7/3-11/9

15x=21-11

x=10/15=>x=1,5

1intreg2/9=(1·9+2)/9=11/9

h) 5x/6=(125/100)⁽²⁵+1/2

²⁾5x/6=³⁾5/4+⁶⁾1/2

10x=15+6

x=21/10=>x=2,1

i) (15/10)⁽⁵+x/4=4

x/4=⁴⁾4-²⁾3/2

x=16-6=>x=10
