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.
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.

Answer:
Yes, because 9 times 12 is 108 and 2 times 48 is 96. So if you add 108+96 you get 204 which can be estimated as 200.
Step-by-step explanation:
The value of the mixed number is A = 27/10
A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.
Given data ,
Let the mixed number be represented as A
Now , the equation will be
A = 2 7/10 be equation (1)
On converting the mixed number to an improper fraction , we get
Multiply the whole number by the denominator and add the numerator to it to get the new numerator of the improper fraction
So , A = [ ( 2 x 10 ) + 7 ] / 10
On simplifying the equation , we get
A = 27/10
Hence , the mixed number to improper fraction is A = 27/10
