Take the ln of both sides
remember
ln(a^x)=xln(a)

xln(2)=ln(22.5)
divide both sides by ln2
x=ln(22.5)/ln(2)

To solve the equation with completing square the numerical value must be on other side of the equation. In this method we multiply linear term’s coefficient with one-half and square it therefore, completing square is suitable method for the equation having leading coefficient is 1 and linear coefficient is even.
