Question

Simplify the following.


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

Answer 1

Answer:

See below ~

Step-by-step 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

Answer 2

Answer:

1,

$\frac{13a}{15b}$

2,

$9$

Step-by-step explanation:

$\frac{3a}{5b} + \frac{4a}{15b}$

$\frac{45a}{75b} + \frac{20a}{75b}$

$\frac{13a}{15b}$

2,

${3}^{6} \times {3}^{0} \div {3}^{4}$

$729 \times 1 \div 81$

$729 \div 81 = 9$
