Answer:
reduce, since 4/5 is smaller than 1
Step-by-step explanation:
3y^-4 × (2y^-4) = 6y^-8
= 6/1/y^8
= 6/y^8
.................................................
1) When x^1 multiply with x^2, 1 will add to 2 and become 3
= x^3
2) y^-1 = 1/y
3^-2 = 1/3^2 = 1/9
5^-2 = 1/5^2 = 1/25
The formula is rad (-6-(-3))^2 + (7-0)^2 which equals 7.6
