Dawson wrote the factorization 3 (power 2) times 5 (power 2).Without finding the actual number,how can you tell if the number is even or odd?

Answers

Answer 1

Answer: An odd number multiplied by an odd number is an odd number. Therefore an odd number squared is also always an odd number.

Answer 2

Answer:

Final answer:

3² x 5² is a multiplication of numbers, none of which are divisible by 2. Hence, the resulting number will be odd, as even numbers require a factor of 2.

Explanation:

The number Dawson wrote is the result of the factorization 3² x 5². Here, 3 and 5 are the bases and the exponents are 2. The exponentiation means the base number is multiplied by itself as many times as the value of the exponent. Therefore, 3² means 3 is multiplied by itself once, and 5² means 5 is multiplied by itself once.

In order to determine if the resulting number is even or odd, we don't have to perform the calculations. For any number to be even, it must be divisible by 2. If there isn't a factor of 2 in the number, the resulting product will be odd.

In this case, neither 3 nor 5 are divisible by 2. Hence, when you multiply them, no matter how many times, the result will always be an odd number. Therefore, the number obtained from 3² x 5² is odd.

Frank is going to plant b vegetable seeds in one garden and 5b + 10 vegetable seeds in another . How many seeds is frank going to plant ?

Answers

The number of seeds that Frank will plant, expressed in algebraic form, is: 6b + 10.

Algebraic Expressions

Given that, b and (5b + 10) are the seeds to be planted by Frank in different gardens, the number of seeds Frank is going to plant can be expressed in algebraic form by adding both expressions together.
Like terms with the same variables are added together.

Thus:

b + 5b + 10

6b + 10

Therefore, the number of seeds that Frank will plant, expressed in algebraic form, is: 6b + 10.
