By what factor must you multiply a number in order to double its square root? With an example.
1 answer:
Suppose it is x = the number
Suppose that h is the factor by which we want to multiply the number to double its square root.
So we have to:
√ (hx) = 2√x.
We solve the equation for us and that:
hx = 4x
h = 4.
You must multiply by 4 to duplicate the square root
