Question

Solve to two decimal places. Use of logarithms. (ln/e)
2^x = 4x-1

Answer 1

2^x ???????

Answer 2

2 raised to the x power

Answer 3

let f(x)=2^x - 4x+1
then f(0)*f(1)<0
so a real root of the given equation lies in between 0 and 1.
Then apply any method of numerical analysis.

Answer 4

Yeah I solved the problem that way but my professor asks for the use of logarithms and or ln/e. Thank you for the reply though

Answer 5

oh i dint read the problem completely. sorry

Answer 6

I ended up with xln2 = ln4x-1 ; but i dont know from there
