If there is a negative exponent, just flip them over for that exponent to be positive. Example: x^-3 would be 1/x³. Thus, 1. 2b²/5a^4 2. (5a³n)³     Distribute the exponent 3 to each term.     5³a^9n³ = 125a^9n³ 3. (x^n+5/y)²     Distribute the exponent 2 to each term.     x^(2n) + 5²/y²     x^(2n) + 25/y²
