simplify-2sqrt(3+\sqrt{5)}sqrt(3-\sqrt{5)}

simplify

- 2 \cdot 3 + 5 \cdot 3 - 5

- 4

Solution steps

- 2 3 + 5 3 - 5

Apply radical rule:

a b = a \cdot b

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

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

(3 + 5) (3 - 5) = 4

= - 24

4 = 2

= - 2 \cdot 2

Multiply the numbers:

2 \cdot 2 = 4

= - 4

(2 \cdot 1 0^{3}) 2 (1.6 \cdot 1 0^{- 19})

x^{2} \cdot (x + 1) \cdot (0.01 \cdot x + 1)^{2}

(6^{2})^{3} 0.216

1 0^{4} \cdot 1 0^{- 8} \cdot 2 π \cdot 6
