Ok I need to work out the sum of the fifth square number and the cube of 3 Help

The square numbers are: 1, 4, 9, 16, 25, 36, 49 etc. The fifth one is 25

The cube of 3 is just 3 cubed, which is 3 x 3 x 3, which equals 27

Therefore the sum of them is 25 + 27 = 52


also express the following numbers as products of thier prime factors

48
56 Wth !

Basically, all this means is what prime numbers would you multiply together to make the number. For example, with 48:

48 can be split into 24 and 2
24 can be split into 12 and 2
12 can be split into 4 and 3
4 can be split in 2 and 2

Therefore, 48 = 2 x 2 x 2 x 2 x 3

Which can also be written as 2^4 x 3

I hope this makes sense :)
