The expression given is log4^x, and we are asked to approximate the value of this expression to four decimal places. To do this, we can use the three given values to interpolate a value for x.
Using the three given values, we can set up a logarithmic equation as follows:
log4^2=0.5
log4^3≈0.7925
log4^5≈1.1610
Solving for x, we get x≈4.1222. Therefore, the approximate value of the given expression to four decimal places is log4^4.1222 ≈ 1.0206.
