Hey i got a questions, im not sure how to solve the following equation for 't'. How would i do it? 2.4 = sqrt(2.1^2 + (0.049*t^2)^2) Thanks

How would i do it? 2.4 = sqrt(2.1^2 + (0.049*t^2)^2) Thanks First square: $\displaystyle 2.4^2 = 2.1^2 + 0.049^2 t^4 $ so: $\displaystyle t^4=\frac{2.4^2-2.1^2}{0.049^2} $ Now find the fourth roots of the rigt hand side and check to see which solve the original equation.
