From the definition of logarithm, we know that:
![$a^y=b\quad\iff\quad y=\log_ab\qquad\quad \,\text{when }a,b\ \textgreater \ 0\,\,\text{ and }\,\,a\neq1](https://tex.z-dn.net/?f=%24a%5Ey%3Db%5Cquad%5Ciff%5Cquad%20y%3D%5Clog_ab%5Cqquad%5Cquad%20%5C%2C%5Ctext%7Bwhen%20%7Da%2Cb%5C%20%5Ctextgreater%20%5C%200%5C%2C%5C%2C%5Ctext%7B%20and%20%7D%5C%2C%5C%2Ca%5Cneq1)
In this case
![a=4](https://tex.z-dn.net/?f=a%3D4)
and
![b=5](https://tex.z-dn.net/?f=b%3D5)
so:
The answer to (8+2-4) and (3-5) is 4
