3%2Froot%284%2C144%29=3%2F144%5E%221+%2F+4%22=3%2F%2812%5E2%29%5E%221+%2F+4%22=3%2F%2812%5E%222+%28+1+%2F+4+%29%22%29=3%2F12%5E%221+%2F+2%22=%0D%0A3%2F%284%2A3%29%5E%221+%2F+2%22=3%2F%284%5E%221+%2F+2%22%2A3%5E%221+%2F+2%22%29=3%2F%282%2A3%5E%221+%2F+2%22%29=%281%2F2%29%283%2F3%5E%221+%2F+2%22%29=%281%2F2%293%5E%221+-+1+%2F+2%22=%281%2F2%293%5E%221+%2F+2%22=3%5E%221+%2F+2%22%2F2=sqrt%283%29%2F2
