Log base 10 is not a number it is just an operator.so log base 10 is not not equal to one but logx base x is 1 where x is any positive number

simple xlog2 = 4X then multiply xlog2 by 0, the 0 = 4 kushneyyyyy
Umelaaniwa wewe!
2^x =4x......log
log2 ^x=log4x.
Xlog2=log(2^2)X.
Xlog2=log(2^2)+logX.
Xlog2=2log2+logX
logX=Xlog2-2log2
logX=(X-2)Log2
X=(X-2)2
X=2X-4
4=2X-X
X=4.
2^x =4x......log
log2 ^x=log4x.
Xlog2=log(2^2)X.
Xlog2=log(2^2)+logX.
Xlog2=2log2+logX
logX=Xlog2-2log2
logX=(X-2)Log2
X=(X-2)2
X=2X-4
4=2X-X
X=4.
acha danganya toto umeambiwa 2X=4X na sio 2^X
Kweli Taifa laangamia yani hesabu ya kitoto tena isiyowezekana 2X=4X NA X=UNDEFINED na si 4 wengine mnaji2ngia maswali yenu.nadhani sasa mmejionea kwamba kufaulu mitihani ni umakini na si kukurupuka kama baadhi ya wa2 humu ALWAYS THINK TWICE BEFORE ZA ACTION

mh ulivyoipoteza log umedanganya mkuu
Mnanikumbusha mbali sana na roho inaniuma
[h=1]SOLUTION: 1. 4x+3y=1, x=1-y 2. 2x-y=6, -x+y=-1 3. 6x-y=3, 4x-2y=-2 4. 2x+3y=7, x=1-4y 5. 2x+3y=6, x-3y=-15 6. 7x-5y=4, y=3x-4 7. 2y-5x=-1, x=2y+5 8. 4x+3y=1, 3x+4y=10 9. 6x-5y=3, 4x+[/h]
jaribu hii basi 3[SUP]x[/SUP]=9X
