The question required e^x \geq x^e \text{ for }x>0
So i got up to e^x \geq e^{elnx}
I'm pretty sure that's right and now I don't know how to get to x^e \text{ from }e^{elnx}
thanks.
hey, can someone tell me the answer for this.
this is my working;
F/l=kII/d
F=kIIl/d
F=k(2I)I(2l)/d
F=4kIIl/d
which is 4 times original so I put D, but the answer says C. Is it because only one wire was doubled?
