Best ResponseYou've already chosen the best response.0take the square root of both sides: \[\sqrt{a^2} = \sqrt{0.36t^{28}}\]\[a=\sqrt{0.36*t^{28}}\] \[a=\sqrt{0.36}*\sqrt{t^{28}}\]do you know what \(\sqrt{0.36}=\)

Best ResponseYou've already chosen the best response.0it is going to be a number, let's call it \(x\), where \(x*x = 0.36\) Is \(x\) going to be larger or smaller than 1?

Best ResponseYou've already chosen the best response.0Right, \[0.6*0.6 = 0.36\] Now what about the \[\sqrt{t^{28}}\]what does that equal?
