There's a problem; it's not an equation. What is it equal to? We can't solve for x unless it's an equation.

that's not an equation. can't solve for x from what you have up there. if it equaled like 1 or zero, then you'd just take the log of both sides so it would be log (base 10) of 1= x^2-4. use a calculator to calculate the log of 1 and then solve for x!!

10^ n = 100,000,... so n= 5 and x^2 -4 = 5, so x^2 = 9....x=+/-3

y=10^(x^2-4) so logy= (x^2-4) (log base 10)
x^2= 4+log y and x = +-sqrt(4+log y)

log of x is equal to plus or minus 2.
