simplify 1/(sqrt(5)+\sqrt{2)}

simplify

\frac{1}{5 + 2}

\frac{5 - 2}{3}

Decimal Notation

0.27395 \dots

Solution steps

\frac{1}{5 + 2}

Multiply by the conjugate

\frac{5 - 2}{5 - 2}

= \frac{1 \cdot ( 5 - 2 )}{( 5 + 2 ) ( 5 - 2 )}

1 \cdot (5 - 2) = 5 - 2

(5 + 2) (5 - 2) = 3

= \frac{5 - 2}{3}

- 4 x - 6 y

(\frac{a ^{3} b ^{- 2}}{b ^{3}})^{2}

3 x - 3 = 15

12 x - 9 y + 15

- ∣ 4 x + 10 ∣ - 4 = - 11
