Solve the following exercise:
462362=
To solve this problem, we'll follow these steps:
- Step 1: Convert the roots to fractional exponents.
- Step 2: Simplify the fractional exponents using properties of exponents.
- Step 3: Determine the simplified expression and verify the answer choice.
Now, let's work through each step:
Step 1: Convert the roots to fractional exponents.
The cube root 362 can be expressed as (62)1/3=62/3.
The fourth root 462 can be written as (62)1/4=62/4=61/2.
Step 2: Simplify the quotient of these fractional exponents.
We have 61/262/3.
Using the property of exponents anam=am−n, we get:
62/3−1/2.
Step 3: Calculate 2/3−1/2.
To subtract these fractions, find a common denominator. The common denominator of 3 and 2 is 6.
- Convert 2/3 to sixths: 3⋅22⋅2=64
- Convert 1/2 to sixths: 2⋅31⋅3=63
Perform the subtraction: 64−63=61.
The expression simplifies to 61/6.
Therefore, the simplified answer is 661, which corresponds to the correct choice: 3.
The solution to the problem is 661.
