Question 1144759
Given 2^m × (1/8)^n = 128 and 4^m ÷ 2^(-4n) = 1/6, find the value of (m-n). 
<pre>I believe you did post this after: test/1144760: Given 2^m × (1/8)^n = 128 and 4^m ÷ 2^(-4n) = 1/16, find the value of (m-n).
If I'm correct, why didn't you DELETE the former?
Why did you allow someone to solve the original problem: "test/1144759," when it contained an error, as itw's SUPPOSED to be: 
{{{matrix(1,7, 2^m * (1/8)^n, "=", 128, "and,", 4^m/2^(- 4n), "=", 1/16)}}}, instead of: {{{matrix(1,7, 2^m * (1/8)^n, "=", "128,", and, 4^m/ 2^(-4n), "=", 1/6)}}}?
BTW, {{{highlight_green(matrix(1,9, m - n, "=", 1&3/5 - - 9/5, "=", 8/5 + 9/5, "=", 17/5, or, 3&2/5))}}}
