Question

Use properties to find 4x23x25

Answer 1

you use the commutative property. you multiply 4 by 25 first, which is 100, and then you multiply it by 23, which is 2300. 

Answer 2

Answer: The required answer is 2300.

Step-by-step explanation: We are given to use properties to find the value of the following product :

`P=4*23*25~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

We will be using the following property :

`(a-b)(a+b)=a^2-b^2.`

Therefore, from (i), we get

`P\\\\=4*23*25\\\\=4*(24-1)*(24+1)\\\\=4(24^2-1^2)\\\\=4(576-1)\\\\=4*575\\\\=2300.`

Thus, the required answer is 2300.
