simplify-2sqrt(196k^8)

simplify

- 2 196 k^{8}

- 28 k^{4}

Solution steps

- 2 196 k^{8}

Apply radical rule:

ab = a b,

assuming

a \geq 0, b \geq 0

196 k^{8} = 196 k^{8}

= - 2196 k^{8}

196 = 14

= - 2 \cdot 14 k^{8}

Apply radical rule:

assuming

a \geq 0

k^{8} = k^{\frac{8}{2}}

= - 2 \cdot 14 k^{\frac{8}{2}}

Divide the numbers:

\frac{8}{2} = 4

= - 2 \cdot 14 k^{4}

Multiply the numbers:

- 2 \cdot 14 = - 28

= - 28 k^{4}

2 (1)^{- 3}

\frac{- 3. 9 ^{2} - 16}{- 3.9 + 4}

\frac{16}{625}

1 - tan^{4} (x)

f (x) - 4
