Answer 1

Given : 7777=10

7777=11

7777=12

7777=13

 7777=14

 7777=15

To find :  Use different operators and symbols

Solution:

7 7 7 7 7 = 12

=>( 77 ÷ 7) + (7 ÷ 7) = 12

(7 + 7) - ( (7 + 7) ÷ 7)  = 12

7777 = 10

(77 - 7)÷ 7 = 10

[√7 + √7  + √7 +  √7]

= [2.64575 + 2.64575  + 2.64575 +  2.64575]

=[ 10.583 ]

= 10

[√7 + √7  + √7 +  √7]  = 10

7 +  [√7 ]   + (7÷ 7) = 10

77 ÷ (√7×√7) = 11

(√7×√7)   +  [√7+√7 ]  = 12

(77 + 7)÷ 7 = 12

7 + 7 - (7÷ 7) = 13

7 + [√7 ] + [√7 ] + [√7 ] = 13

7777=14

7 + 7 + 7 - 7 = 14

(√7×√7)  + (√7 ×√7)  = 14

7777=15​

7 + 7 + (7÷ 7) = 15
