Answer:3 b − 2 c− d , t o 3 , 3 + 3d − 3 b

Step-by-step explanation:

( b − c ) ⋅ 3 + ( c -d ) raise t o 3 3 + ( d − b ) ⋅ 3

Write the problem as a mathematical expression.

( b − c ) ⋅ 3 +( c − d ) raise t o3 3+ ( d − b) ⋅ 3

Remove parentheses.

( b − c) ⋅ 3 + c − d , t o 3 , 3 + ( d − b ) ⋅ 3

Simplify each term.

Apply the distributive property.

b ⋅ 3 − c ⋅ 3 + c− d

Move 3 to the left of b . 3 ⋅ b − c ⋅ 3 + c − d

Multiply 3 by − 1 ⋅ 3 b − 3 c + c − d

Add − 3 c and c. 3 b − 2 c − d , t o 3 , 3 + ( d − b ) ⋅ 3

Simplify each term.

Apply the distributive property.

3 + d ⋅ 3 − b ⋅ 3

Move 3 to the left of d . 3 + 3 ⋅ d − b ⋅ 3

Multiply 3 by − 1 . 3 + 3 d − 3 b
