(t^-4)^-9t^2
a. t^26
b. t^-26
c. t^38
d. t^-38

Well, the power of -9t will be 'replaced by a power of -9 which is a similar of the replacement

Then, t^36 (t^2) which would give you the result of "t" to the power of 36 + 2

I wish I can show you what I mean by those steps more understanding for you. So, sorry.

This is what I mean in other words, by the way!

t ^ 36 + 2 = t^38

So, therefore, your result would have to ▶ t^36

T^26 ❌(This IS NOT your answer)

T^-26❌ (⬅This IS NOT your answer)

T^38 ✔ (⬅This IS your answer)

T^-38❌ (⬅This IS NOT your answer)

Good Luck!
