    Watu wametumia hesabu za high prime numbers kuingiza encryption katika computer na hivyo kuondoa ufisadi katika computer, acha kufikiri kwamba hesabu hazina maana katika maisha. Kama hujui/ huwezi hesabu sema tu.

    Utawezaje kufanya accounting na kujua kama pesa zinaibiwa na mafisadi bila kujua hesabu rahisi tu?

    Are you serious?

    Hii hesabu ilileta ubishi mwingi sana.

    Ukifanya kwa log hautomaliza.

    Chora graph ya y=4x na graph ya y=2[SUP]x[/SUP]hapo kwenye intersection ya hizo graph ndo jibu lako.

    Husninyo alidanganya kwenye solution yake.

    Graphical method is the most apropriate appropriate y=2^x then linear eqn y=2x record the intersection points as u answer

    2^x=4xSoln:introduce ln both sidesxln2=ln(4x)xln2=ln4+lnxxln2=ln(2*2)+lnxxln2=ln2+ln2+lnxxln2-ln2-ln2=lnx(x-1-1)ln2=lnxln2(x-2)=lnxThen introduce e both sides gives2(x-2)=x2x-4=x2x-x=4x=4The anser is 4Proof:2^4=164*4=16therefore 2^4=4*4
