Question

Which method do you prefer when comparing numbers written in scientific notation? Explain why you prefer this method using examples. PLS HURRY

Answer 1

The general form in scientific notation is

• z.z ×10^z

where z is integer

So while comaparing

We usually compare z.z rounded to similar significant numbers .

In rest case

• we use power of 10 ,the number which has higher that's bigger.

Example

• 1.27×10⁴
• 1.24×10⁴

First one is bigger

Answer 2

If two numbers have the same exponent for 10, then compare the decimal numbers to determine the greater number. Sometimes you may have to compare two numbers, but only one of them is in scientific notation. In that case, convert the number that is not in scientific notation into scientific notation first. Then, compare the two numbers. Example 1 : Compare 5.62 x 10 6 and 7.39 x 10 5.
