Value Assessment Challenge: Finding the Greatest Number
Question
Choose the largest value
Video Solution
Solution Steps
00:00Choose the largest value
00:03 Calculate the quotient
00:06Calculate the square root of 9
00:10Convert from the root of the fraction to the root of the numerator and the root of the denominator
00:13Calculate each root, and calculate the quotient
00:27Calculate the quotients
00:35The square root of 6 is less than square root of 9
00:41We know that 4 squared equals 16
00:45Therefore the square root of 18 is definitely greater than 4, thus greater than 3
00:49This 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: 436=436=26=3
Choice 2: 1636=1636=46=1.5
Choice 3: 636=636=66≈2.45 (approximating since it is irrational)
Choice 4: 236=236=26=26×2=32≈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 is the largest.
