Jibu la uongo
Jibu la uongoJibu ni 7 the rest nmemuuliza bard, je njia hapo kwa picha..View attachment 2803130View attachment 2803131
Draw a graph of y=8x and that of 2^(8-x) on the same x-y plain then lookHabari za wakati huu wana jamiiforum
Kuna ka swali hapa ka O level kana sumbua hivyo nataka kuwasirisha kwa watabe wa jamii forum ila niweze kupata solution yake
SWALI :
2^(8-x) = 8x
Yaani :
Two power eight minus X equals to eight x(eight times X )
Find the value of X.
Asante ,
nahitaji soulution , si jibu pekee !
Ni kwamba tulikua tunacomplicate au vp🤣🤣🤣2^{8-×}=8×
Solution
2^{8-×}=2^3×
8-×=3×
8=4×
×=2
WEka njiaVery simple
la saba b,WEka njia
Ukisubstitute X=7 kwenye equation mbona LHS na RHS hazilingani?. LHS=2,RHS=56. Au nimepuyanga?Jibu ni 7 the rest nmemuuliza bard, je njia hapo kwa picha..View attachment 2803130View attachment 2803131
Jibu Ni mbili ,
ume-prove jibu lako???? 2^(8-7)= 8x7????Jibu ni 7 the rest nmemuuliza bard, je njia hapo kwa picha..View attachment 2803130View attachment 2803131
Kudadeq🤣🤣🤣That is what i meant hicho kialama ^ kina ifanya equestion kuonekana hivyo
Hapo ku sovle sasa ni mtereko kama kitonga introduce log
Usichanganye madesaMkuu kama hawashughuliki na decimals ina maana ukiapproximate hilo jibu la 3.2 inakuwa ni 3, sasa je ukipachika hiyo 3 pale kwenye X jibu la LHS na RHS litafanana, yaani kwamba 2^5 = 8×3 siyo
Hio njia yangu na ya dronedrake zote ni sahihi na zinatoa jibu sahihi
Kama nilivyosema approximately ya jibu ni x= 3.25 kwa mfano.....na dronedrake amesema x= 3,28
Haya tuzitie kwenye swali
2^(8 - 3.28) = 8 x 3.26
26.35 = 26.24
Haya chaka liko wapi hapa???????
Ngoja nimuite mkali wa maths Mokaze
Haya tuoneshe wewe hiyo njia na jibu kama hii sio sawa....This can’t be true. You’ve assumed that 8x and 2^(8-x) are factors?
Jibu Ni mbili ,
