Question

Whats (4.2×10^6)+(2.25 × 10^5) in scientific form

Answer 1

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
