-12y+14-9y=14
-21y=0
y=0, x=7

The exponential form of this equation is "0.8⁴ = 0.4096 ".
Now, in this logarithm equation the base of the log is 0.8.
when we convert this equation to exponential form 0.8 will go to left side, 4 moved up and became the exponent of 0.8 and thus it makes the exponential equation;
4=log₀.₈ 0.4096   <span>logarithmic equation
0.8</span>⁴ = 0.4096      exponential form
        
             
        
        
        
About 12 would be the correct answer i may be wrong but i worked it out and got that idk how but i did
