What is the composition of the soil?Kama uzi unavyojieleza, ningependa kujua wadudu waishio ardhini wanapataje hewa?
Mfano?Si kila mdudu anatumia hewa unayotumia wewe.... Kuna wengine Wanatumia Co2

uko vizuri mkuu, hongera!let 1st digit=a
2nd=b
3rd=c
4th=d
5th=e
1.a=(b)2
2.b+c=10
3.d=b+1
4.e+c=14
5.a+b+c+d+e=30
=> (b)2+b+c+d+e=30 (a=(b)2)
=> (b)2+b+(10-b)+d+e=30 (b+c=10=>c=10-b)
=> (b)2+b+(10-b)+(b+1)+e=30 (d=b+1)
=> (b)2+b+(10-b)+(b+1)+(14-(10-b)=30(e+c=14=>e=14-c=>14-(10-b))
=> (b)2+b+10-b+b+1+14-10+b=30
=> (b)2+2b+15=30
=> (b)2+2b=30-15
=> (b)2+2b-15=0
=> (b)2+5b-3b-15=0
=> b(b+5)-3(b+5)+=0
=> (b+5) (b-3)=0
=> b+5=0 b-3=0
=> b= -5 b= 3
Value ya b itakuwa 3 kwa sababu kwenye pin yoyote hakuna negative digit
b = 3
Kwa ku-substitute equation za hapo juu tunapata
1st digit=9
2nd=3
3rd=7
4th=4
5th=7
