Solve (y^-2)^-3

$$( y ^ { - 2 } ) ^ { - 3 }$$

Evaluate

$$y^{6}$$

Steps for Raising Power to Another Power

Use the rules of exponents to simplify the expression.

$$\left(y^{-2}\right)^{-3}$$

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

$$y^{-2\left(-3\right)}$$

Multiply -2 times -3.

$$y^{6}$$

Differentiate w.r.t. y

$$6y^{5}$$

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).

$$-3\left(y^{-2}\right)^{-3-1}\frac{\mathrm{d}}{\mathrm{d}y}(y^{-2})$$

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}.

$$-3\left(y^{-2}\right)^{-4}\left(-2\right)y^{-2-1}$$

Simplify.

$$6y^{-3}\left(y^{-2}\right)^{-4}$$
