simplify sqrt(5*(\sqrt{2)-1)^2}

simplify

5 \cdot (2 - 1)^{2}

(2 - 1) 5

Decimal Notation

0.92620 \dots

Solution steps

5 (2 - 1)^{2}

Apply radical rule:

ab = a b, a \geq 0, b \geq 0

5 (2 - 1)^{2} = 5 (2 - 1)^{2}

= 5 (2 - 1)^{2}

Apply radical rule:

a^{2} = a, a \geq 0

(2 - 1)^{2} = 2 - 1

= 5 (2 - 1)

= (2 - 1) 5

\frac{( - 16 ) ^{3}}{( 4 ^{- 2} ) ^{- 3}}

sec (x) cos (x)

\frac{csc ( x ) cos ( x )}{tan ( x ) + cot ( x )}

sec^{4} (x) - tan^{4} (x)
