Answer 1

6,4×10 сверху над 10 двойка

Answer 2

Ответ:

(1.6*10^(-5))*(4*10^7)= 6.4*10^7*4*10^(-5)*10^2=25.6*10^4

Answer 3

To multiply two numbers written in scientific notation, you can multiply their coefficients and add their exponents. Let's calculate the multiplication of the given numbers:

(1.6×10^10-5) × (4×10^7)

First, multiply the coefficients: 1.6 × 4 = 6.4

Then, add the exponents: 10-5 + 7 = 10^2 (since -5 + 7 = 2)

Putting it all together, the result is: 6.4 × 10^2

Therefore, the expression (1.6×10^10-5) × (4×10^7) simplifies to 6.4 × 10^2.
