simplify (d^2)/(d^2x)(x^2)

simplify

\frac{d ^{2}}{d ^{2} x} (x^{2})

x

Solution steps

\frac{d ^{2}}{d ^{2} x} (x^{2})

Apply rule:

(a) = a

(x^{2}) = x^{2}

= \frac{d ^{2}}{d ^{2} x} x^{2}

Cancel the common factor:

d^{2}

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

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{1 \cdot x ^{2}}{x}

Apply rule:

1 \cdot a = a

1 \cdot x^{2} = x^{2}

= \frac{x ^{2}}{x}

Simplify

\frac{x ^{2}}{x} : x

= x

a^{3} + b^{3}

\frac{7 i}{- 4 + 8 i}

5 \frac{3}{5}

16 \cdot (- 3)

2^{- 2} + 4
