I am not familiar with "brighten" but this is how you can expand and use the distributive property:
7(256)
= 7(200 + 50 + 6)
= 7(200) + 7(50) + 7(6)
= 1400 + 350 + 30
= 1780
Answer:
D
Step-by-step explanation:
Answer:
-m^2 |n|^3 sqrt(n)
Step-by-step explanation:
-sqrt( m^4n^7)
We know that sqrt(ab) = sqrt(a) sqrt(b)
-sqrt(m^4) sqrt(n^7)
The sqrt(m^4) = m^2
The sqrt(n^7) = sqrt(n^6) sqrt(n) = |n|^3 sqrt(n) We take the absolute value because if n is negative, n^6 is postive, but n^3 is negative
-sqrt(m^4) sqrt(n^7)
-m^2 |n|^3 sqrt(n)
