Question

(0,2⋅107)⋅(1,8⋅10−2) =

Answer 1

Ответ:

342,4

Объяснение:

0,2×107=21,4

1,8×10=18

18-2=16

21,4×16=342,4

Answer 2

To calculate the product of two numbers written in scientific notation, you need to multiply their coefficients and add their exponents. Here's the calculation:

(0.2 x 10^7) x (1.8 x 10^-2)

First, multiply the coefficients: 0.2 x 1.8 = 0.36

Next, add the exponents: 7 + (-2) = 5

So, the result is 0.36 x 10^5.

However, scientific notation typically has one non-zero digit before the decimal point. To put the number in standard scientific notation form, we can rewrite it as:

0.36 x 10^5 = 3.6 x 10^4
