Answer 1

5 1/3 =16/3
a² -b² =(a -b)(a +b)

(16/3 +3/16 -(16/3 -3/16))(16/3 +3/16 +(16/3 -3/16) =(16/3 +3/16 -16/3 +3/16)(16/3 +3/16 +16/3 -3/16) =(3/16 +3/16)(16/3 +16/3) =6/16 * 32/3 =(6*32) /(16*3) =2*2 =4

Answer 2

(5 1/3 + 3/16)^2 - (5 1/3 - 3/16)^2=

= [(5 1/3 + 3/16) - (5 1/3 - 3/16)]*[(5 1/3 + 3/16) + (5 1/3 - 3/16)]=

= (3/16+3/16)*(5 1/3 + 5 1/3) = 6/16*10 2/3 = 3/8*32/3 = 4
