Answer 1

X= √2 , -√2
or x ≈ 1.41 , -1.41

I hope this helps ya out :)

Answer 2

Answer:

± 707.106

Step-by-step explanation:

㏒($2x^{2} +2$)= 6

$10^{log(2x^{2} +2)} = 10^{6}$

$2x^{2} +2 = 10^{6}$

$2(x^{2} +1) = 10^{6}$

$x^{2} +1= \frac{10^{6}}{2}$

$x^{2} +1= 500000$

$x^{2}= 500000-1$

$x^{2}= 499999$

X = $\sqrt{499999}$

x = ± 707.106
