Solve x^-2x-1=0 - ScanMath

Evaluate

x^{- 2} \times x - 1 = 0

Find the domain

x^{- 2} \times x - 1 = 0, x \neq = 0

Multiply the terms

More Steps

x^{- 1} - 1 = 0

Move the constant to the right-hand side and change its sign

x^{- 1} = 0 + 1

Removing 0 doesn't change the value,so remove it from the expression

x^{- 1} = 1

Express with a positive exponent using a^{- n} = \frac{1}{a ^{n}}

\frac{1}{x} = 1

Cross multiply

1 = x

Swap the sides of the equation

x = 1

Check if the solution is in the defined range

x = 1, x \neq = 0

Solution

x = 1
