Solve {left(1/xright)}^-2

$${ \left( \frac{ 1 }{ x } \right) }^{ -2 }$$

Evaluate

$$x^{2}$$

Steps for Raising Power to Another Power

Use the rules of exponents to simplify the expression.

$$\left(\frac{1}{x}\right)^{-2}$$

To raise a power to another power, multiply the exponents.

$$x^{-\left(-2\right)}$$

Multiply -1 times -2.

$$x^{2}$$

Steps for Raising Quotient to a Power

Use the rules of exponents to simplify the expression.

$$\left(\frac{1}{x^{1}}\right)^{-2}$$

To raise the quotient of two numbers to a power, raise each number to the power and then divide.

$$\frac{1^{-2}}{\left(x^{1}\right)^{-2}}$$

To raise a power to another power, multiply the exponents.

$$\frac{1}{x^{-2}}$$

Multiply 1 times -2.

$$\frac{x^{2}}{1}$$

Differentiate w.r.t. x

$$2x$$

Steps Using Chain Rule

If F is the composition of two differentiable functions f\left(u\right) and u=g\left(x\right), that is, if F\left(x\right)=f\left(g\left(x\right)\right), then the derivative of F is the derivative of f with respect to u times the derivative of g with respect to x, that is, \frac{\mathrm{d}}{\mathrm{d}x}(F)\left(x\right)=\frac{\mathrm{d}}{\mathrm{d}x}(f)\left(g\left(x\right)\right)\frac{\mathrm{d}}{\mathrm{d}x}(g)\left(x\right).

$$-2\times \left(\frac{1}{x}\right)^{-2-1}\frac{\mathrm{d}}{\mathrm{d}x}(\frac{1}{x})$$

The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of ax^{n} is nax^{n-1}.

$$-2\times \left(\frac{1}{x}\right)^{-3}\left(-1\right)x^{-1-1}$$

Simplify.

$$2x^{-2}\times \left(\frac{1}{x}\right)^{-3}$$
