Question

(t^-4)^-9 t^2

A t^26
B t^-26
C t^38
D t ^-38

Answer 1

T^38

How to solve: just combine using the basic rules of powers

Answer 2

Its c

Explanation:

The relevant rules of exponents are

.. (t^a)^b = t^(a·b)

.. t^a·t^b = t^(a+b)

You have

.. (t^-4)^-9·t^2

.. = t^((-4)*(-9) +2)

.. = t^38 . . . . . . . . . . . selection C
