simplify (2-sqrt(x))(2-sqrt(x))

simplify

(2 - x) (2 - x)

4 - 4 x + x

Solution steps

(2 - x) (2 - x)

Apply exponent rule:

aa = a^{2}

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

= (2 - x)^{2}

Apply Perfect Square Formula:

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

(2 - x)^{2} = 2^{2} - 2 \cdot 2 x + (x)^{2}

= 2^{2} - 2 \cdot 2 x + (x)^{2}

2^{2} = 4

- 2 \cdot 2 x = - 4 x

(x)^{2} = x

= 4 - 4 x + x

(8.6 \cdot 1 0^{- 7}) (2.5 \cdot 1 0^{- 2})

e^{(- \frac{l n ( 2 )}{2.7 \cdot 24} \cdot 1.5)}

(\frac{m}{lp})^{4}

(0.1 m) (0.2 mn) (10 m^{2} n^{2})
