Respuesta :

for 1 significant figure the first number must be above 0 but the rest must be 0 so the answer would be 90000

Answer:

90000

Step-by-step explanation:

A significant figure is a number different from zero that assigns the value of the quantity.

In this case, you have four significant figures, not counting the zeros. To round this, you need the first upper number with only one significant figure.

For that, we use 9 because is the next number from 8, and then complete the value with zeros.

87600.2 will be 90000.0
