Answer:

6.49 × 10⁷ years

Step-by-step explanation:

For Dinosaurs

Dinosaurs have been extinct for about 6.5×10 exponent seven years

6.5 × 10⁷ years

For Neanderthals

Neanderthals have been extinct for about 3.0×10 exponent four years

= 3.0 × 10⁴ years

How many longer is calculated by Subtraction

6.5 × 10⁷ years - 3.0 × 10⁴

= 64970000 years

= 6.49 × 10⁷ years
