Question

find x if (-2/3)–¹³=(-2/3)¹-²x​

Answer 1

Answer:

Step-by-step explanation:we have

(-2/3)^-13 × (3/-2)^8=(-2/3)^-2x+1

=》(-2/3)^-13 ×(-2/3)^-8=(-2/3)^-2x+1

when base are equal then power will also equal

=》-13 +(-8)=-2x+1

=》-13-8-1=-2x

=》-22=-2x

cancelling (-) from both sides

22=2x

=》22/2=x

=》11=x
