I did my math igcse already this is what I always do.
=2304(pi)
then write
"wavy sign* 2300(pi)
then on your answer area write
2300(pi)

is the answer k+1?
if it is just change the 5^y to k because it tell you to express it in k.

Waalaikumassalam wr wb...
remember a^m x a^n = a^(m+n) ???

similarly...if it's 5^(y+1) you can write it as 5^y x 5^1 = k x 5 = 5k
