Question

the product of 8mn and (7mn+5m-3) step by step explanation pls fast​

Answer 1

Answer:

$8m(7mn + 5m - 3) \\ 56 {m}^{2} n + 40 {m}^{2} - 3$

Answer 2

Given,

The numbers 8mn and (7mn + 5m -3)

To Find,

The product of these two numbers.

Solution,

First of all we must write down the equation in the correct form,

8mn x (7mn + 5m -3)

[We must multiply 8mn with all the numbers present in the brackets]

Therefore we can write it down as,

= (8mn x 7mn) + (8mn x 5m) - (8mn x 3)

= $56m^{2} n^2$ + $40m^{2} n$ - 24mn

Therefore the required answer is,

$56m^{2} n^2$ + $40m^{2} n$ - 24mn

✔We must multiply a given number with all the numbers present in the brackets separately.
