`206 xx 71 - 12080 = ?`

The value of (5.71 xx 5.71 xx 5.71 - 2.79 xx 2.79 xx 2.79 )/( 5.71 xx 5.71 + 5.71 xx 2.79 xx 2.79 + 2.79 ) in simplified form is :

96 107 129 162 206 ?

If 18xx12=206 and 19xx22=408 , then 23xx36=?

The value of (5. 71xx5. 71xx5. 71-2. 79xx2. 79xx2. 79)/(5. 71xx5. 71+5. 71xx2. 79+2. 79xx2. 79) is (a) 2.82 (b) 2.92 (c) 8.5 (d) 8.6

Which property involved in the simplification of 2 xx (71xx 5) ?

If 18xx12=206" and "19xx22=408," then "23xx36= ?
