It is known that the M + 1 power of 5 multiplied by the m power of 2 - the M + 1 power of 5 multiplied by the m power of 2 is equal to 4 multiplied by 25 multiplied by 3. Find the value of M

5^(m+1)x2^m-5^mx2^(m+1)=4x25x3
5^mx2^m*(5-2)=4x25x3
3*5^m*2^m=3x4x25
5^m*2^m=(2x5)^2
(5*2)^m=(2x5)^2
m=2

Let set M = {x | - 1 ≤ x ≤ 2} set n = {x | - K ≤ 0} if M ∩ n ≠ 0, find the value range of K

N: X is less than or equal to K because the intersection is not empty, so K is greater than or equal to - 1. The answer is k is greater than or equal to - 1
