I may be wrong but I think the answer is B.
Numbers less than 1 have a negative exponent
Here there are 2 digits after decimal point so the answer is
5 * 10^-2
Answer:
X>5/4
Step-by-step explanation:
What is the solution to x 4 – 12x 2 + 10 > 0?
Answer:

Step-by-step explanation:
Let's re-write the equations in order to get the variables as separated in independent terms as possible \:
First equation:

Second equation:

Third equation:

Now let's subtract term by term the reduced equation 3 from the reduced equation 1 in order to eliminate the term that contains "y":

Combine this last expression term by term with the reduced equation 2, and solve for "x" :

Now we use this value for "x" back in equation 1 to solve for "y":

And finally we solve for the third unknown "z":

Is the answer D ? I think it is
