Answer 2

either 100, 10, 316.266 , or 2

Answer 3

i got x=2,−2

Answer 4

10^5 = x^(2)+1
x^(2)= 10^(5) - 1
x= +- square root of 10^(5) - 1

Answer 5

so then the answer would be 316.266?

Answer 6

yes. It should have two answers. +3160266 and -316.266. Assuming that your log is log to base 10. Since you only have one choice i guess 316.266 is the best answer
