I need to find x of this equation:
1.0221044505936159^x + 1.0446975079232772^x + 1.0677899723724409^x + 1.091392883061106^x + 1.1155175231229544^x + 1.140175425099138^x + 1.1653783764512973^x + 1.1911384251964328^x + 1.2174678856663448^x + 1.24437934439437^x + 1.2718856661322526^x + 1.3287357857717006^x + 1.3581067603002603^x + 1.3881269640841731^x + 1.4188107479794378^x + 1.3^x == 21
Most probably, it's not possible to solve it analytically but numerically...
I tried Mathematica, but the respond was like:
The equations appear to involve the variables to be solved for in an essentially non-algebraic way.
Any idea if there is a numerical solver online that could solve it? How about Matlab?
