pleaseee help me :(((( meterinya operasi eksponen bilangan bulat

x = -3 & y = 5
a. x^-2 = -3^-2 = 1/-3^2 = 1/9
b. 3y^-2 x³ = 3(5)^-2 × -3³ = 15^-2 × -27 = 1/15^2 × -27 = 1/225 × -27 = -27/225 = -3/25
c. x^-1 + y^-2 = 1/x + 1/y² = 1/3 + 1/5² = 1/3 + 1/25 = 25/75 + 3/75 = 28/75
d. x^-2 - y^-2 = -3^-2 - 5^-2 = 1/-3² - 1/5² = 1/9 - 1/25 = 25/225 - 9/225 = 16/225
e. (-4y²)^-3 = (-4(5)²)^-3 = -100^-3 = 1/-100³ = 1/-100000
f. x³/y^-1 = -3³/5^-1 = -27/1/5 = -27 × 5 = -135
g. 3(x-y)^-3 = 1/(3x-3y)³ = 1/27x³-27y³ = 1/27(-3)³-27(5)³ = 1/-729 - 27(125) = 1/-729 - 3375
h. 6(x^-3 - y^-3) = 6(-3^-3 - 5^-3) = 6 (1/-3³ - 1/5³) = 6 (1/-27 - 1/125)
