Question

Multiply 0.00032 cm by 4.02 cm and express the answer in scientific notation. Remember to follow significant figure rules.

Answer 1

`\text{The product in standard form = }1.28* 10^(-3)\:\:cm^2`

Explanation:

One length is given to be 0.00032 cm

Second length is given to be 4.02 cm

Now, To find the product of the two quantities :

Product = First Length × Second Length

= 0.00032 × 4.02

= 0.0012864 cm²

Now, we need to represent the obtained product into the standard form

`\text{So, The product in standard form = }1.28* 10^(-3)\:\:cm^2`

Answer 2

The answer is 1.3 * 10⁻³ cm²

0.00032 cm * 4.02 cm = 0.0013 cm²

0.0013 cm² = 1.3 * 0.001 cm² = 1.3 * 10⁻³ cm²
