Question

How does 48 squared equal 4*3^2?

Answer 1

\[\sqrt{48}= 4\sqrt{3} \]

Answer 2

\[48=16\times 3\] not
\[4\times 9\]

Answer 3

\[\sqrt{16\times 3}=\sqrt{16}\sqrt3=4\sqrt3\]

Answer 4

Oh, and so the three stays squared because you can't reduce it or "resquare" it anymore?

Answer 5

the 3 stays in because 3 is not a perfect square, i.e. the square root of 3 is an irrational number, not an integer

Answer 6

whereas even i know that the square root of 16 is 4

Answer 7

Haha, alright, thanks :) One questio though, could you set it up 48 equals 24 x 2?

Answer 8

Or since both are irrational numbers, you can't set it up that way?

Answer 9

look at first 2 lines
48 squared is not the same as square root of 48
