Dr Venter compared his discovery of using cell to grow artificial life with using baking powder to make cake rise. Comment if this is a fair comparison and will there be any implication in his discovery.

A wall measuring 245cm by 280cm is to be completely covered by square tiles. Find the minimum number of square tiles needed.

245 = 5 x 7 x 7
280 = 2 x 2 x 2 x 5 x 7

HCF = 5 x 7
So the square tile must have side of 5 x 7 = 35cm.

So the number of tiles needed = 7 x 2 x 2 x 2 = 7 x 8 = 56

Given that 360 = 2Cube x 3square x 5
a) the smallest integer, j, such that 360 x j is a perfect square
b) the smallest integer, k, such that 360 x k is a perfect cube
Find the j & k

To get a perfect square, all the power must be even number.
To get a perfect cube, all the power must be multiple of 3.

So
a) j=2 x 5
b)k=3 x 5square
