   ocr: SQUARES AND SQUARE ROOTS SMALL. 2 above a number tells Aus that the number is to be - - 2) - multiplied by itself- that is to say, - the number is to be squared. Ifwe square 2 and9 we get: 2(2x2)=4 - 9(9x9)=81 Having multiplied 2 by 2 to find the square, it follows that the square - - - - - 3 root of4is 2. Likewise, the square root of 81is9.This can be written: 2 Finding the square V4=2 Multiply aside number by the 2 same number along the bottom v81=9 tofind the. sq uare ofthat number.
