Question

$\frac { 5 ^ { - 4 } } { 3 } \times \frac { 5 ^ { - 5 } } { 3 } = \frac { 5 ^ { 3 x } } { 3 }$
Help me to Find the value of x ​

Answer 1

Step-by-step explanation:

we know that a^m × a^n = a^(m+n)

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

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

Now comparing the powers as base are same:

we get, -9=3x

x= -9/3

x= -3
