if 2^2x+2 * 5^x-1= 8^x*5^2x

Question

if 2^{2x+2 *} 5^x-1=8^{x *} 5^2x ; then 10^x is :

 

 

Answer 1

2^(2x+2)x 5^(x-1) = 8^xx 5^2x

 

2^(2x+2) x 5^(X-1) = (2³)^X x5^2x

 

if the bases are the same then the exponents are equal

 

2x + 2= 3x

        2= x

but:

x - 1 = 2x

     -1= x

 

they are not the same

Are your exponents correct?
