The reciprocal of -9/11 is 11/-9. When using the reciprocal you must always flip the fraction. I'll give some examples:
2/3 is 3/2
4/9 is 9/4
1/16 is 16/1
I hope this helps you!

For this case we have that by definition of properties of powers and roots, it is fulfilled that:

\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}

So:

\sqrt [4] {9 ^ {\frac {1} {2} x}} = 9 ^ {\frac {\frac {1} {2}} {4} x} = 9 ^ {\frac {1} {8} x}

So, we have to:

\sqrt [4] {9 ^ {\frac {1} {2} x}} = 9 ^ {\frac {1} {8} x}

Answer:

9 ^ {\frac {1} {8} x}9

Write your own word problem and share it with the group. Then translate your problem into its resulting math equation. What step

Ainat [17]

Step-by-step explanation:

Word Problems are mathematical problems presented in complete languages, rather than in mathematical notations.

Example:

A certain number is divided by half, the result is added to itself to give 6, what is the number?

Solution:

- Let the number be x

- Divide x by half:

In word problem, extra caution is to be taken, as misinterpretation can be very chaotic. Dividing a number by 2, is totally different from dividing the number by half.

4 divided by 2 is 4÷2 = 2

4 divided by half is 4÷½ = 4×2/1 = 8

2 and 8 are different, reason to be cautious.

So dividing x by half, we have:

x ÷ 1/2 = x × 2/1 = 2x.

- Now, what we have is

2x + x = 6

Solving this equation, we can obtain the value of x.

2x + x = 6

3x = 6

Dividing both sides by 3

3x/3 = 6/3

x = 2.

Therefore, the solution to the word problem is x = 2.

In 2010 Singapore welcome 11600000 overseas visitors.This value has been rounded off to the nearest 100000.What are the largest

spayn [35]

Answer:

The largest possible number of overseas visitors would be 11,640,000.

The smallest possible number of overseas visitors would be 11,550,000.

Step-by-step explanation:

The number 11,600,000 was rounded off to the nearest 100,000.

This means that either 0 or 1 was added to the figure with place value of 100,000.

It would be zero (0) in the case where the number after the 100,000th placed value number is lower than 5 and it would be one (1) in the case where the number after the 100,000th placed value is greater than or equal to 5.

Therefore, the largest possible number of overseas visitors would be 11,640,000.

The smallest possible number of overseas visitors would be 11,550,000.
