Question

round the following measurement the 3 significant figures and put it into standard scientific notation. 1.3458 kg to enter scientific notation use the \e\ form. for example if your answer is 3.45 x 10^5 then enter 3.45e5 (no spaces).

Explanation:

Step1: Identify significant - figure rules

When rounding to 3 significant figures, we look at the fourth digit. If it is 5 or greater, we round up the third digit.

Step2: Round the number

The number is 1.3458. The fourth digit is 5, so we round up the third digit. 1.3458 rounds to 1.35.

Step3: Convert to scientific notation

In scientific notation, a number is written as \(a\times10^{n}\), where \(1\leq a < 10\) and \(n\) is an integer. For 1.35, in the "e" form, it is 1.35e0.

Answer:

1.35e0
