Answer:
3/4
Step-by-step explanation:
(-7/8)³ × (-7/8)⁸ = (-7/8)¹¹ = (-8/7) ^(3x-2) { by using a^m × a^n = a^(m+n)}
(-7/8)¹¹ = (-7/8) ^-(3x-2) { by using a^(-1) = 1/a}
(-7/8)¹¹ = (-7/8) ^(-3x+2) { when base are same then the powers are equal }
Therefore, -3x+2=11
x = -3
therefore (3/4)^(X+4) = (3/4)¹ = 3/4
