Answer 2

So remember your rule of exponents?
\[\Large\rm \left[~r~\right]^{ab}=\left[(r)^a\right]^b\]We can apply it to this problem:\[\Large\rm \left[~1.04~\right]^{4x}=\left[(1.04)^4\right]^x\]

Answer 3

still dont get it

Answer 4

So let's throw our \(\Large\rm (1.04)^4\) into our calculator and see if it gives us one of the options.

Answer 5

So approximating we get,
\[\Large\rm \left[\color{orangered}{(1.04)^4}\right]^x=\left[\color{orangered}{1.1699}\right]^x\]Applying the exponent rule changes the inner part like that ^
