Question

Виконайте обчислення і запишіть результат у стандартному вигляді: (2,6•10^3)•(4,5•10^-8)​

Answer 1

Ответ:

2.6×4.5= 11.7

10³×10^-8= 10^3-8=10^-5

11.7×10^-5=1.17×10^-4

Answer 2

I can help you with calculations and scientific notation. To perform the calculation, you need to multiply the coefficients and add the exponents of 10. The result should be in the form of a x 10^b, where 1 ≤ a < 10 and b is an integer. Here are the steps:

(2,6•10^3)•(4,5•10^-8)​ = (2,6 x 4,5) x (10^3 x 10^-8) = 11,7 x 10^(3-8) = 11,7 x 10^-5

To write the result in standard form, you need to move the decimal point 5 places to the left. The result is:

0,000117

You can also use online tools to convert between scientific notation and standard form, such as [this one](https://www.calculatorsoup.com/calculators/math/scientific-notation-converter.php) or [this one](https://www.calculatorsoup.com/calculators/math/scientificnotation.php). You can also watch some videos that explain how to calculate with scientific notation, such as [this one](https://www.youtube.com/watch?v=ZtB0vJMGve4), [this one](https://www.youtube.com/watch?v=_BtzXojuM1o), or [this one](https://www.youtube.com/watch?v=yX6Mq9whsX0). You can also read some articles that explain the rules and examples of scientific notation, such as [this one](https://byjus.com/maths/scientific-notation/) or [this one](https://www.houseofmath.com/encyclopedia/numbers-and-quantities/numbers/scientific-notation/how-to-calculate-with-scientific-notation).
