Create an instructional idea showing how to solve an exponential equation

Equation Requirements

Create an exponential equation in the form m = k x 2^(bx+c) + d

you can choose whatever numbers (negative / fractions / decimals are a bonus) for m, k, b, c and d.

it has to have a solution that is irrational (no ‘easy’ problems where x ends up being a whole number or fraction)

and k and at least one other value are not 0 or 1!

Be sure to explain WHY you’re doing the steps you’re doing to solve the equation.
