Question

(2.9*10^-2)(8*10^-3)

Answer 1

2,9*8*10^-5= 0,000232

Answer 2

Ответ:

0, 000232

Объяснение:

$(2, 9 * 10^{-2})(8 * 10^{- 3}) = (2, 9 * (\frac{1}{10})^{2})(8 * (\frac{1}{10})^{3}) = (2, 9 * 0, 01)(8 * 0, 001) = 0, 029 * 0, 008 = 0, 000232$

Answer 3

To multiply numbers in scientific notation, you can simply multiply the coefficients and add the exponents.

Let's multiply the numbers you provided:

(2.9 * 10^-2) * (8 * 10^-3)

Multiplying the coefficients gives us:

2.9 * 8 = 23.2

Adding the exponents gives us:

10^-2 * 10^-3 = 10^(-2+(-3)) = 10^-5

Therefore, the result is:

23.2 * 10^-5

In scientific notation, we typically express the coefficient as a number between 1 and 10, so we can rewrite it as:

2.32 * 10^-4
