Answer 2

x = 7

Step-by-step explanation:

(-3/7)^5 × (-7/3)^-2 = (-7/3)^-x

=> (-7/3)^-5 × (-7/3)^-2 = (-7/3)^-x [ Since (a/b)^n = (b/a)^-n ]

=> (-7/3)^-5+(-2) = (-7/3)^-x [ Since a^m × a^n = a^m+n ]

=> (-7/3)^-7 = (-7/3)^-x

Since bases are same powers can be compared.

Therefore,

-7 = -x

x = 7 [ When on both sides of the equal sign, there is a minus sign, they get cancelled and the answer is positive.]
