Value Assessment Challenge: Finding the Greatest Number

Question

Choose the largest value

Video Solution

Solution Steps

00:00 Choose the largest value
00:03 Calculate the quotient
00:06 Calculate the square root of 9
00:10 Convert from the root of the fraction to the root of the numerator and the root of the denominator
00:13 Calculate each root, and calculate the quotient
00:27 Calculate the quotients
00:35 The square root of 6 is less than square root of 9
00:41 We know that 4 squared equals 16
00:45 Therefore the square root of 18 is definitely greater than 4, thus greater than 3
00:49 This is the solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Simplify each choice using the Square Root Quotient Property.
  • Step 2: Calculate the square root of each simplified fraction.
  • Step 3: Compare these values to find the largest one.

Now, let's work through each step:

Step 1: Simplify each choice:
Choice 1: 364=364=62=3 \sqrt{\frac{36}{4}} = \frac{\sqrt{36}}{\sqrt{4}} = \frac{6}{2} = 3
Choice 2: 3616=3616=64=1.5 \sqrt{\frac{36}{16}} = \frac{\sqrt{36}}{\sqrt{16}} = \frac{6}{4} = 1.5
Choice 3: 366=366=662.45 \sqrt{\frac{36}{6}} = \frac{\sqrt{36}}{\sqrt{6}} = \frac{6}{\sqrt{6}} \approx 2.45 (approximating since it is irrational)
Choice 4: 362=362=62=6×22=324.24 \sqrt{\frac{36}{2}} = \frac{\sqrt{36}}{\sqrt{2}} = \frac{6}{\sqrt{2}} = \frac{6 \times \sqrt{2}}{2} = 3\sqrt{2} \approx 4.24

Step 2: Evaluate to find which is the largest value:
Choice 1 equals 3, Choice 2 equals 1.5, Choice 3 equals approximately 2.45, and Choice 4 approximately equals 4.24.

Step 3: Compare these values. Clearly, 4.24 4.24 is the largest.

Therefore, the solution to the problem is 362 \sqrt{\frac{36}{2}} .

Answer

362 \sqrt{\frac{36}{2}}
