Question

Find n if (2^228/2^n)=512

Answer 1

Here is your answer...

___________________

We know
$\frac{ {2}^{228} }{ {2}^{n} } = 512 \\ \\ {2}^{228 - n} = 512 \\ \\ {2}^{9} = 512 \\ \\ {2}^{228 - n} = {2}^{9} \\ \\ 228 - n = 9 \\ \\ 228 - 9 = n \\ \\ n = 219$

we know


Hope this helps you......

Answer 2

n= 219

2^228-n= 2^9
n=219
