simplify (sqrt(w)-sqrt(z))(sqrt(w)-sqrt(z))

simplify

(w - z) (w - z)

w - 2 w z + z

Solution steps

(w - z) (w - z)

Apply exponent rule:

aa = a^{2}

(w - z) (w - z) = (w - z)^{2}

= (w - z)^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(w - z)^{2} = (w)^{2} - 2 w z + (z)^{2}

= (w)^{2} - 2 w z + (z)^{2}

(w)^{2} = w

(z)^{2} = z

= w - 2 w z + z

ln (x^{2}) \frac{x}{y}

k^{0.5} \cdot (\frac{16 k}{5})^{0.5}

5.25 \cdot 1 0^{- 7}

- 5 a^{2} b^{2} (2 a^{2} b^{2} - 5 a + 2 b)
