I don't think you needed to use the power rule for logs as it’s implied from canceling the base with the log of the same base leaving with whatever is in the exponent on one side of the equation.

x-y = 2, x = 2 + y 2^(2+y) - 2 ^y = 4 2^y * (2^2 - 1) = 4 2^y = 4/3 y = (log 4-log3) / log2 = 0.4150 X = 2.4150

4=2^X-2^Y=2^Y（2^（X-Y）-1）=2^Y（2^2-1）=3*2^Y，2^Y=4/3， Y=LOG（4/3）/LOG（2）=2-LOG（3）/LOG（2），X=4-LOG（3）/LOG (2)

Oxford admission to what ? To the "course of equity and verieties " 😂😂😂

2^x-2^y=4 x-y=2 -----> y=x-2 2^x-2^(x-2)=4 2^x-¼(2^x)=4 4(2^x)-2^x=16 3(2^x)=16 2^x=⅓(2⁴) 2^(x-4)=⅓ x-4=log_2(3^-1) x-4=-log_2(3) x=4-log_2(3) ❤ y=4-log_2(3)-2 y=2-log_2(3) ❤
