Hey guyss i need with 3 of these questions : )
i'm supposed to express these with positive exponents
1. 2a^-4/5b^-2
2. (5a^3n)^3
3. (x^n+5/y)^2

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
