Question

if 3 by 4 to the power minus 4 into 3 by 4 to the power 3 X equals to 3 by 5 to the power 5 then find the value of x³​

Answer 1

Answer:

Hii

Step-by-step explanation:

( 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
