Question 93276
1. 4x^3/4 = 108 (exponent is 3/4) 
{{{4x^(3/4) = 108}}}
{{{x^(3/4) = 27}}}
{{{x = 27^(4/3)}}}
{{{x = (3^3)^(4/3)}}}
{{{x = (3)^(3*4/3)}}}
{{{x = 3^4}}}
{{{x = 81}}}
2. e^x * 4e ^2x+1 (the 2x+1 are all in superscript/exponents)
{{{e^x * 4e^(2x + 1)}}}
{{{4(e^x * e^(2x + 1))}}}
{{{4e^(x + 2x + 1)}}}
{{{4e^(3x + 1)}}}
3. 5^ x-1 = 125^2x+3 ( the x-1 and 2x+3 are exponents/superscript)
{{{5^(x - 1) = 125^(2x + 3)}}}
{{{5^(x - 1) = (5^3)^(2x + 3)}}}
{{{5^(x - 1) = 5^(3(2x + 3))}}}
{{{5^(x - 1) = 5^(6x + 9)}}}
{{{x - 1 = 6x + 9}}}
{{{-10 = 5x}}}
{{{-2 = x}}}
