Write 45 in the form k squareroot 5 where k is an integer

This question is impossible.

Step-by-step explanation:

Explanation:

I got this question on a practice maths paper, and it has to be a mistake.

The previous answer posted here says that 45 = 9√5, which is clearly wrong:

We know that 45 = 9 x 5 but this person has said 45 = 9 x √5, and clearly 5 √5.

To add, the mark scheme of the practice paper I did said that the answer was 3√5 which is also wrong.

I think the question meant to ask "Write √45 in the form k√5 where k is an integer" in which case the answer 3√5 would be correct:

√45 = √9 x √5

√9 = 3

Therefore, √45 = 3√5

I hope this answers your question!

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
