1.rezolvati ecuatiile : a) 3 x X + 124 = 784 , b) 14 x X + 25 < 68
2.calculati 312 :3 + 74 x 9
3.calculati 25 la puterea 5 : 5 la puterea 4 - 768 la puterea 0.
4. efectuati : {[(80-6x7)x3+6]x2-100}x2+50
RAPID VA ROG!!!!!!

Răspuns :

a. 3*x+124=784
3x=784-124=660
x=660/3=220

b.14*x+25<68
14x<68-25
14x<43
x<43/14

2.
312:3+74*9=104+666=770
3. 25^5:5^4-768^0=5^10:5^4-1=5^6-1=15625-1=15624
4.{[(38*3)+6]*2-100}*2+50=[(114+6)*2-100]*2+50=(240-100)*2+50
=280+50=330
