hello

to solve this problem, we need use law of indicies


(a^m)/(a^n)=a^(m-n)

now we having know this, we can proceed to solve our problem here


(16b^(42))/(4b^(25))

step 1, let's seperate them and use the expression above to solve it


\begin{gathered} (16b^(42))/(4b^(25))=(16)/(4)b^(42-25) \\ (16)/(4)b^(17) \end{gathered}

step 2

divide 16 by 4


\begin{gathered} (16)/(4)b^(17) \\ 4b^(17) \end{gathered}
