Answer 1

Answer:

Step-by-step explanation:

Hey there !

Solution:

This is a sum based on Ratio and Proportions.

1 calculation = 0.0000034 seconds

Which is 1 calculation = 3.4 × 10⁻⁶ seconds. This implies 4000 calculations will be ?

1 : 3.4 × 10⁻⁶ :: 4000 = ?

=> 4000 × 3.4 × 10⁻⁶

=> 4 × 10³ × 3.4 × 10⁻⁶

=> 13.6 × 10⁻³ seconds.

Hence the calculator would take  13.6 × 10⁻³ seconds.

Hope my answer helped !
