-2=3-7^5 radical x^2
-2=3-16807radical x^2
-2=3-16807 • IxI
Reduce the index of the radical and the exponent with 2
16807 x |x| - 2 = 3
Move to left side
16807 x |x| - 2 + 2 = 3 + 2
Add 2 to both sides
16807 x |x| = 5
|x| = 5/16807
Divide both sides by 16807
x= 5/16807
x= -5/-16807 (only use one negative)
Use the absolute value definition and rewrite the absolute value equation as two separate equations
X_1 = 5/16807
X_2 = -5/16807
“_” underscores are meant to be subscripts
