What is the answer of this t²= 81
Answer (1)
t = 9, t = -9We're asked to solve the following equation:[tex]\sf t^2=81[/tex]So first of all we should recall that equations are solved by isolating the variable, which is t in this case.Take the square root of both sides.Note that in the result we'll have not one, but two solutions:[tex]\sf t=9,t=-9[/tex]
