Choose the largest value
To solve this problem, we'll follow these steps:
Let's simplify each expression:
Choice 1:
Simplify: since .
Choice 2:
Simplify: since .
Choice 3:
Simplify: since .
Choice 4:
Simplify: since .
Upon comparing the values, is the largest.
Therefore, the largest value is .
Choose the expression that is equal to the following:
\( \sqrt{a}:\sqrt{b} \)
The numerators alone don't tell the whole story! Even though 64 is the largest numerator, you need to divide by the denominator first. For example, but .
Not always! You can compare perfect squares directly. Since 8 > 7 > 6 > 5, we know without calculating decimals.
That's fine! You can still compare square roots of any positive numbers. If , then always holds true.
Yes, but try the mental math approach first! Simplifying fractions like 64÷8=8 is faster than calculating decimal approximations, and it builds your number sense.
Remember: larger input means larger output for square roots. Since √8 has the largest number under the radical, it gives the largest result!
