Answer:

1.9 ×
10^(7)

Explanation:

To calculate the population in New York we require to multiply

7600 × 2.5 ×
10^(3) ← express 7600 in scientific notation

= 7.6 ×
10^(3) × 2.5 ×
10^(3)

= (7.6 × 2.5) ×
10^((3+3))

= 19 ×
10^(6) ← express 19 in scientific notation

= 1.9 ×
10^(1) ×
10^(6)

= 1.9 ×
10^((1+6))

= 1.9 ×
10^(7)
