Question

(-2/3) ^ -13 * (-2/3) ^ 8 = (-2/3) ^ (-2x + 1)​

Answer 1

Answer:

x=3

Step-by-step explanation:

(-2/3)^-13 * (-2/3)^8 = (-2/3)^(-2x+1)

since base is same we will add the powers

(-2/3)^(-13+8) = (-2/3)^(-2x+1)

(-2/3)^(-5) = (-2/3)^(-2x+1)

since base is same,

equating powers

-5= -2x+1

-5-1 = -2x

-6 = -2x

-6/-2= x

3= x

Answer 2

Answer:

1^2x-6

Step-by-step explanation:

(-2/3)^(-13)×(-2/3)^(8) = (-2/3)^(-2x+1)

(-2/3)^(-5) = (-2/3)^(-2x+1)

(-2/3)^5×3/(-2)^(-2x+1)

1^(-5)/1^(-2x+1)

1^-5+2x-1

1^-6+2x

1^2x-6
