let u = 4^x then u - u/4 = 24 3u = 96 u = 32 so, 4^x = 2^5 but 4^x = 2^(2x), so 2x = 5 x = 5/2 (2x)^x = 5^(5/2) = 25√5

slope of first line = -1/2 slope of 2nd line = -a/3 to be perpendicular, they must be negative reciprocals of each other, or, when multiplied we should get -1 (-1/2)(-a/3) = -1 a/6 = -1 a = -6

Trial and error -- but it didn't take long. 2^2 = 4 4 - 4 = 0 >> Nope. It's not 2. 3^2 = 9 9 - 6 = 3 >> Yep! That works. Obviously 4 is not the answer either.

The triangle formed by connecting the midpoints is similar to the original triangle but with all lengths half the original. Therefore the area of the triangle is four times the area of the little one inside (1/2) b h = 4 (1/2)(b/2)(h/2)

25! 25...........1 The question is how many numbers between 25 and 1 are divisble by 5 25 = 5 times 5 20 = 5 times 4 15 = 5 times 3 10 = 5 times 2 5 = 5 times 1 5^6 so, I think m = 6 is the answer.

4^(x)-4^(x-1)=24 4^(x-1) (4 - 1) = 24 4^(x-1) = 8 (2^2)^(x-1) = 2^3 2^(2x-2) = 2^3 then 2x-2 = 3 2x = 5 and x = 5/2 thus: (2x)^x = (5)^(5/2) = (√5)^5 = 25√5
