(3.4)^2x+3 = 8.5. Solve for x
The Attempt at a Solution
3.4^2x = 8.5/3.4^3 ( divide the equation by 3.4^3. This bit i am not sure about)
2xlog3.4 = log (8.5/3.4^3
x = log (8.5)- 3log(3.4) / 2 log (3.4)
x = -0.626
This seems to work out when i plug it in to the original equation.
Is there an insert equation icon on the template. Can`t find it!
