if 5^x 25^2y = 1 and 3^5x 9^y= 1/9,find the value of x and y.
Answered by Steve
5^x 25^2y = 1
5^x 5^4y = 1
5^(x+4y) = 1
x+4y = 0

3^5x 9^y = 1/9
3^5x 2^2y = 3^-2
5x+2y = -2

x = -4/9
y = 1/9

if (-2 1 x+2 )
(3 x-4 5 ) =25
(0 1 3 )


a) find the value of x

b) hence ,find (-2 1 x+2 )^-1
( 3 x-4 5 )
(o 1 3 )

p/s : all the value above IS COMBINE in one bracket ( )
