A field of 3.9 mi^2 is being subdivided into 1.3×10^3 family gardens. How many square miles will there be in each garden? Write the answer in scientific notation

Answer 1

To find the area of each garden, we need to divide the total area of the field (3.9 mi^2) by the number of gardens (1.3×10^3).

3.9 mi^2 / (1.3×10^3) = (3.9/1.3) × (mi^2/10^3)
= 3 × 10^(-1) × mi^2

Since the area is in square miles, the answer should be written as 3 × 10^(-1) sq mi in scientific notation.

Answer 2

Charlee is using her calculator to find the product of two large numbers. Her calculator shows 1.78E12 on the display. Interpret what this means

Answer 3

The number 1.78E12 is in scientific notation. It represents a very large number, specifically 1.78 multiplied by 10 to the power of 12.

So, 1.78E12 = 1.78 × 10^12.

In other words, the number on the calculator display is equal to 1.78 multiplied by 1 followed by 12 zeros, which is equivalent to 1,780,000,000,000.
