Since 10 is a positive the opposite must be negative. Opposite integer of 10 is -10 ( negative 10).
Happy studying ^-^
I seen your comment on the other persons thing, it should be 60° :) correct me if i’m wrong!
We are going to rewrite both numbers:
(4.2 × 10 ^ 6) = 4200000
(2.25 × 10 ^ 5) = 225000
Adding we have:
4200000 + 225000 = 4425000
Rewriting in exponential notation we have:
4425000 = 4,425 * 10 ^ 6
Answer:
(4.2 × 10 ^ 6) + (2.25 × 10 ^ 5) is equal to:
4,425 * 10 ^ 6
