Find all the real fourth roots of 256. 4 -8 and 8 8 -4 and 4

1 answer:

3 0

256 = 16^2. In turn, 16=4^2.

The 4th roots are {4, 4, -4 and -4}.

Check for yourself: Does 4^4= 256? does (-4)^4 = 256?

Answer:

No. GCF = 2

$2(x^2 - 5x + 10)$

$2(x^2 - 5x + 10)$ $(\dfrac{-5}{2})^2=(-2.5)^2 =6.25$

$2[x^2 - 5x+6.25-6.25 + 10]$

$2[(x^2 - 5x+6.25)-6.25 + 10]$

$2[(x - 2.5)^2-6.25+ 10]$

$2[(x - 2.5)^2+3.75]$

$2(x - 2.5)^2+7.5$
