(0.9)^t-4 rewrite the function to determine if its exponential growth or decay.

I get the part where its 0.9^t over 0.9^4, then it would be 0.9^t over 0.7, but then the answer in the book is 1.52(0.9)^t. I would like to know where the 1.52 came from.

...and then, since .9 < 1, it is a decay function.
