Question

(2,2*10^-10)*(3*10^3)=?

Answer 1

Ответ:

$6.6*10^{-7}$

Пошаговое объяснение:

Мы перемножаем первые части чисел, а затем складываем степени десяток

$2.2*10^{-10} *3*10^{3} =6.6*10^{-7}$

Answer 2

To multiply these two numbers, we can use the rules of scientific notation. The general form of a number in scientific notation is a × 10^b, where a is a number between 1 and 10, and b is an integer exponent.

Let's multiply the given numbers:

(2.2 × 10^(-10)) × (3 × 10^3)

When multiplying numbers in scientific notation, you can multiply the coefficients (the numbers before the powers of 10) and add the exponents. Therefore:

(2.2 × 3) × (10^(-10) × 10^3)

6.6 × 10^(-7)

The final answer is 6.6 × 10^(-7).
