simplify (sqrt(7)-5)*(sqrt(7)-5)

simplify

(7 - 5) \cdot (7 - 5)

32 - 107

Decimal Notation

5.54248 \dots

Solution steps

(7 - 5) (7 - 5)

Apply exponent rule:

aa = a^{2}

(7 - 5) (7 - 5) = (7 - 5)^{2}

= (7 - 5)^{2}

Apply Perfect Square Formula:

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

(7 - 5)^{2} = (7)^{2} - 27 \cdot 5 + 5^{2}

= (7)^{2} - 27 \cdot 5 + 5^{2}

(7)^{2} - 27 \cdot 5 + 5^{2} = 32 - 107

= 32 - 107

(- 2)^{3}

(e^{x} - e^{- x}) (e^{a} - e^{- a})^{- 1}

2^{- x} cos (x)

1.24 \times 1 0^{- 10}

(4.49 x 1 0^{10}) x (1.81 x 1 0^{10})
