Question

Simplify the following.

I need to see a step by step answer on both questions to see how it actually works.

Answer 1

1,

`(13a)/(15b)`

2,

`9`

Explanation:

`(3a)/(5b) + (4a)/(15b)`

`(45a)/(75b) + (20a)/(75b)`

`(13a)/(15b)`

2,

`{3}^(6) * {3}^(0) / {3}^(4)`

`729 * 1 / 81`

`729 / 81 = 9`

Answer 2

See below ~

Explanation:

27. (B)

• 3a/5b + 4a/15b
• Take the LCM to be 15b
• 3a(3) + 4a / 15b
• 13a/15b

27. (C)

• (3²)³ × 3⁰ ÷ 3⁴
• 3⁶ x 1 ÷ 3⁴
• 3²
• 3 x 3
• 9
