Write the Expression in standard form by expanding and combining like terms 4 (8m-7n) + 6 (3n-4m)

Standard for is x * 10 ^I

where,

I = indice

10 > x < 0

you cannot write this is standard form with putting in what they stand for. However you can simplify it -

4 (8m-7n) + 6 (3n-4m)

32m - 28n + 18n - 24m

8m - 10n

but hey I am from England do what we call standard form might be different
