Option 2) 0.4
Option 3) 12
Option 4) 5/13
Option 5) 0.02

Answer 1

Each given number can be rewritten as a square by finding its square root. The numbers provided are 0.81, 0.16, 144, 25/169, and 0.0004, with the square roots being 0.9, 0.4, 12, 5/13, and 0.02, respectively.

Step-by-step explanation:

Rewriting Numbers as Squares

The student has asked to rewrite the number 'a' as a square for the following numbers: 0.81, 0.16, 144, 25/169, and 0.0004. To find the square root of each number, we must determine which number, when multiplied by itself, results in the given number. Here are the square roots for each:

• √0.81 = 0.9, which makes it Option 1)
• √0.16 = 0.4, which makes it Option 2)
• √144 = 12, which makes it Option 3)
• √25/169 = 5/13, which makes it Option 4)
• √0.0004 = 0.02, which makes it Option 5)

Therefore, each number rewritten as a square is listed alongside its corresponding option.
