Rewrite each multiplication or division expression using a base and an exponent
brilliants [131]

Using the laws of indices , 4⁵ ÷ 4² can rewritten as 4³.

<h3>What is the result of the division in exponent form?</h3>

Given the expression; 4⁵ ÷ 4²

To perform the division operation, we use one of the laws of indices;

n^a/n^b = n^{a-b}

Given that;

  • n = 4
  • a = 5
  • b = 2

Now, we apply the laws of indices ;

4⁵ ÷ 4² = 4⁵⁻² = 4³

Therefore, using the laws of indices, 4⁵ ÷ 4² can rewritten as 4³.

Answer:

A)

3a2 – 2b2 – 2c2 – ab + 5ac + 5bc

(3a + 2b - c)(a - b + 2c) \\  = (3 {a}^{2}  - 3ab + 6ac + 2ab - 2 {b}^{2}  + 6bc - ac + bc - 2 {c}^{2} ) \\  = 3 {a}^{2}  - ab + 5ac - 2 {b}^{2}  + 5bc -  {2c}^{2}  \\  = 3 {a}^{2}  - 2 {b}^{2}  -  {2c}^{2}  - ab + 5ac + 5bc
