What it's telling you to do is take the nth root of something raised to the mth power. Without the m, it would look like this.
Without the n it would look like this.
When they are put together, it looks like this.
Answer:
Mean = £1.8 million
Step-by-step explanation:
The MEAN is the sum of all the numbers divided by the number of numbers.

Hence the mean is million
Using a system of equations, it is found that she has 9 picture books.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Number of picture books.
- Variable y: Number of encyclopedias.
- Variable z: Number of fairy tale books.
The ratio of the number of picture books encyclopedias, and fairy tale books Annette had is 3:4:5, hence:
She gave half of her encyclopedias to her brother and he gave her 5 books of fairytales. Now she has 14 more books of fairy tales than encyclopedias, hence:
z + 5 - 0.5y = 14.
z - 0.5y = 9
From the ratios, we have that:
Hence we solve for x to find the number of picture books:
x = 9.

You have to do 45 divided by 2. Hopefully there is not tax!
Answer:
190 people
Step-by-step explanation:
At lunch, there were 120 people.
There were 3 times more people at lunch than breakfast meaning you divide 120 by 3.
120 / 3 = 40
At dinner, there were 10 people less than at breakfast.
40 - 10 = 30
Add up your numbers.
120 + 40 + 30 = 190
B = 40
L = 120
D = 30
