join sqrt(4+k^2)*sqrt(13)

join

4 + k^{2} \cdot 13

13 (k^{2} + 4)

Solution steps

4 + k^{2} 13

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

13 k^{2} + 4 = 13 (k^{2} + 4)

= 13 (k^{2} + 4)

x - 9 \cdot x + 9

\frac{1}{4} (4.83 \cdot 1 0^{- 6})

- 1.6021917 \cdot 1 0^{- 19}

7.9 \cdot 1 0^{- 3}
