Question

(3,6⋅10^4):(1,2⋅10^-3)

Answer 1

$\displaystyle \tt \frac{3,6\cdot10^{4}}{1,2\cdot10^{-3}}=\frac{3,6\cdot10^{4}\cdot10^{3}}{1,2}=3\cdot10^{7};$

Answer 2

36000÷0.0012=30000000

Answer 3

To divide two numbers written in scientific notation, you need to follow these steps:

Step 1: Divide the coefficients (the numbers before the powers of 10). Step 2: Subtract the exponent of the denominator from the exponent of the numerator. Step 3: Write the result in scientific notation.

Let's apply these steps to the given expression: (3.6 × 10^4) ÷ (1.2 × 10^-3)

Step 1: Divide the coefficients: 3.6 ÷ 1.2 = 3.

Step 2: Subtract the exponent of the denominator from the exponent of the numerator: 4 - (-3) = 4 + 3 = 7.

Step 3: Write the result in scientific notation: 3 × 10^7.

So, (3.6 × 10^4) ÷ (1.2 × 10^-3) = 3 × 10^7.
