## smartgirl101 Group Title . Evaluate: t^-ca^ca, where c = 3, a = 2, and t = -4 2 years ago 2 years ago

just substitute $\LARGE t^{-c}\cdot a^c\cdot a$ $\LARGE (-4)^{-3}\cdot 2^3\cdot 2$ $\LARGE \left(\frac{1}{-4}\right)^{3}\cdot 16$ Continue... :)

the ^c is suppose to be with the (a) that you multiplied with at the end

3. Kreshnik Group Title

well.. I'm confused, O_O you should have used parentheses ... is it $\Huge t^{-ca^{ca}}$ can you draw it ? :(
