Answer 1

A)
(x⁻⁴ * x⁻²)⁻⁵ : (x⁻⁶ * x⁻⁴)⁻²/ (x⁻⁸ : x⁻⁹)⁶ = (x⁻⁴⁻²)⁻⁵ : (x⁻⁶⁻⁴)⁻² / (x⁻⁸ ⁺ ⁹)⁶ = 
 = (x⁻⁶)⁻⁵ : (x⁻¹⁰)⁻² / (x¹)⁶ = x³° : x²⁰ / x⁶ = x³⁰⁻²⁰ : x⁶ = x¹⁰ : x⁶ = x¹⁰⁻⁶ =
 x⁴ = ( - 1/4)⁴ = 1/256
b)
[x¹⁰ : (x⁻⁴)⁻²] * [(x⁻²)⁻⁶ * x] * x⁻²/(x⁻⁴ : x⁻³⁰)² : x³⁷ = 
 = [x¹⁰ : x⁸] * [x¹² * x] * x⁻²/(x⁻⁴⁺ ³°) : x³⁷ = x¹⁰⁻⁸ * x¹²⁺¹ * x⁻²/x²⁶ : x³⁷ = 
 = x² * x¹³ * x⁻² / x²⁶⁻³⁷ = x¹³ : x ¹¹ = x¹³⁻¹¹ = x² = (- 2)² = 4
