When multiplying powers with the same base you write the result as a base raised to the power that is the sum of previous two powers:

For example,


The answer is actually 7.0 because the lengths of the triangle are both going to be 5 and the hypotenuse is then 5 square root of 2 which is 7.07 so if you round it’s 7.0
1/2 (2) + 3 + 5.3 (3)
1 + 3 + 15.9
19.9
Scale factor is used by architects or engineers to transfer their prototype idea to large-scale use. If the volume of a prism is 20, you need to multiply its dimensions with a scale factor to find the new volume which is 540. For example, if the volume is doubled, this means you used a scale factor of 2. Hence, you just have to divide the new volume by the smaller volume.
Scale factor = 540/20
Scale factor = 27
