If 2^x - 2^(x-2) = 3(2^13), what is the value of x?

LHS = 2^x - 2^(x-2) = 2^x - 2^x *2^-2 = 2^x - 2^x /2^2 = 2^x - 2^x /2^2

= 2^x - 2^x /4 = (4*2^x - 2^x)/4

2^x(4-1) = 4*3(2^13)

2^x(3) = 4*3(2^13)

2^x = 4(2^13)

2^x = 2^15

x = 15

M-1 = F+1

Solve these two equation and you will get F= 5 and M= 7

How many members are on the team?

12
