Question

Find the value of x for which 5 by 3 raise to power minus 4 x 5 by 3 raise to power minus 5 is equal to 5 by 3 raise to power 3 x

Answer 1

( 5/3 )^-4 × ( 5/3 )^-5 = ( 5/3 )^3x

**************************************

By exponential laws :

1 ) a^m × a^n = a^m+n

2 ) If a^m = a^n then m = n

*********************************

( 5/3 )^-4-5 = ( 5/3 )^3x

( 5/3 )^-9 = ( 5/3 )^3x

-9 = 3x

-9/3 = x

-3 = x

Therefore ,

x = -3
