f: \(4x-5^4:5^2=75\)
=>\(4x-5^2=75\)
=>4x-25=75
=>4x=25+75=100
=>\(x=\frac{100}{4}=25\)
g: \(36:x+2^3\cdot2^2=36\)
=>\(36:x+2^5=36\)
=>36:x=36-32=4
=>x=36/4=9
h: \(25^{x}\cdot5^{x+1}=125\)
=>\(5^{2x}\cdot5^{x+1}=125\)
=>\(5^{3x+1}=5^3\)
=>3x+1=3
=>3x=2
=>x=2/3
i: \(\left(3x+4\right)^2+3^2\cdot3=127\)
=>\(\left(3x+4\right)^2=127-27=100\)
=>\(\left[\begin{array}{l}3x+4=10\\ 3x+4=-10\end{array}\right.\Rightarrow\left[\begin{array}{l}3x=6\\ 3x=-14\end{array}\right.\Rightarrow\left[\begin{array}{l}x=2\\ x=-\frac{14}{3}\end{array}\right.\)
