rezolvati ecuatiile
a. 0,1 la puterea 4*0,3 la puterea 3*10 la puterea 2-x=3,008
b. 20,09*02 la puterea 2+x=2010 la puterea 0
c. [(1,5 la puterea 2+x)*0,2]/0,1=10
d. [12+(57,3-x)/0,1]/10 la puterea 2=3

Answer 1

a. 0,1⁴*0,3³*10²-x=3,008
0,0001*0,0,027*100-x=3,008
x=0,00027-3,008=-3,00773

b. 20,09*0,2²+x=2010⁰
20,09*0,04+x=1
x=1-0,8036
x=0,1964

c. [(1,5²+x)*0,2]/0,1=10
(2,25+x)*0,2=1
2,25+x=5
x=5-2,25
x=2,75

d. [12+(57,3-x)/0,1]/10²=3
12+(57,3-x)/0,1=300
(57,3-x)/0,1=300-12
(57,3-x)/0,1=288
57,3-x=28,8
x=57,3-28,8
x=28,5
