Question

. Evaluate: t^-ca^ca, where c = 3, a = 2, and t = -4

Answer 1

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... :)

Answer 2

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

Answer 3

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

Answer 4

ok...
