What is the best estimate for the sum of 3/8 and 1/12

Answers

Answer 1

Answer: I would round the 8 in 3/8 to ten, along with roundin the 12 in 1/12 to 10 as well. Now you would have 3/10 + 1/10, = 4/10 or 2/5 simplified. Hope this helps, (as this would be my estimate!)

Answer 2

Answer: The best estimate would be 11/24, actually that is the exact...

Answer:

$(1)/(8a^9b^12)$

Step-by-step explanation:

$((a^(-3))/(2b^4))^3 =$

$= ((1)/(2a^3b^4))^3$

$= (1)/(8a^9b^(12))$

Answer:To simplify the expression "a raised to the negative third power over quantity 2 times b raised to the fourth power end quantity all cubed", we can follow these steps:

Step 1: Simplify the numerator.

a raised to the negative third power is equivalent to 1 over a cubed.

Step 2: Simplify the denominator.

2 times b raised to the fourth power is equivalent to 2b to the fourth power.

Step 3: Combine the simplified numerator and denominator.

So, the expression becomes 1 over a cubed divided by 2b to the fourth power, all cubed.

Step 4: Simplify the division.

When we divide by a fraction, we can multiply by its reciprocal.

The reciprocal of 2b to the fourth power is 1 over 2b to the fourth power.

Therefore, the expression simplifies to 1 over a cubed times 1 over the reciprocal of 2b to the fourth power, which is 1 over 2b to the fourth power.

In summary, the simplified expression is 1 over 2b to the fourth power times a cubed.
