Math Problem Statement
Solution
This image includes multiple math questions regarding prime factorization, perfect squares, and perfect cubes. Let's break down each part:
Part (a): Express 129,600 as a product of its prime factors.
- To solve this, we'll perform prime factorization on 129,600.
Part (b): Using the answer from part (a), explain why 129,600 is a perfect square.
- After the prime factorization, we'll analyze if each prime factor has an even exponent, which would confirm it is a perfect square.
Part (c): Given that and are prime numbers, find the values of and such that is a perfect cube.
- We'll need to adjust the prime factorization of 129,600 by multiplying it with and dividing by in such a way that the resulting expression is a perfect cube.
Let me first handle part (a) by finding the prime factorization of 129,600. sympy as sp
Finding the prime factorization of 129600
number = 129600 prime_factors = sp.factorint(number) prime_factorsThe prime factorization of 129,600 is:
For part (b): To check if 129,600 is a perfect square, we observe the exponents of the prime factors. For a number to be a perfect square, each prime factor's exponent must be even.
In this case:
- The exponent of is 6 (even),
- The exponent of is 4 (even),
- The exponent of is 2 (even).
Since all exponents are even, 129,600 is indeed a perfect square.
Now, let's move to part (c), where we need to find prime numbers and such that is a perfect cube. I'll calculate this next.To make a perfect cube, the exponents of all prime factors must be multiples of 3.
Currently, the prime factorization of 129,600 is , with the following exponents:
- For , we have (which is a multiple of 3, so no change needed).
- For , we have (we need to add 2 to make it a multiple of 3).
- For , we have (we need to add 1 to make it a multiple of 3).
Therefore, to make a perfect cube:
- We can multiply by (to increase the exponent of 3 to 6),
- We can divide by (to increase the exponent of 5 to 3).
Thus, and .
