SQUARE ROOTS

For many years mnemonics have been employed to memorise useful figures to several decimal places by constructing sentences that contain words of different lengths, each word-length representing each different digit.

Here are some sentences to recall square roots (each to 3 dec.places):

a). For the square root of 2:

" I wish I knew
( 1 . 4 1 4 ) the root of two "

b). For the square root of 3:

" O charmed was he
( 1 . 7 3 2 ) to know the root of three "

c). For the square root of 5:

" So now we strive
( 2 . 3 2 6 ) to know the root of five "

d). For the square root of 6:

" We need more logistics
( 2 . 4 4 9 ) to know the root of six "
