my question is
7m^4n-7mn^4​

Answer 1

Given: The term 7m^4n - 7mn^4

To find: Factorise the given term.

Solution:

• Now the given term is 7(m^4)n - 7m(n^4)

• Taking common terms out, we get:

                 7mn(m³ - n³)

• Now we know the formula:

                 a³ - b³ = (a - b)(a² + ab + b²)

• Applying this, we get:

                 7mn(m - n)(m² + mn + n²)

Answer:

            So the factors are 7mn(m - n)(m² + mn + n²)

Answer 2

answer-7mn(m-n)(m²+mn+n²)

step by step explanation

we take common from the two term and we get 7(m³-n³)MN

now we can see m cube into n cube verify the formula that says that

a³ - b³ = (a-b)(a²+ab+b²)

therefore

7(m³-n³)MN=7mn(m-n)(m²+mn+n²)
