Question

1) 72 + [ 62 – ( 102 – 4 . 16 )]
 

Answer 1

7² + [6² - (10² - 4.16)]

= 49 + [36 - (100 - 64)]

= 49 + [36 - 36]

= 49 + 0

= 49

Answer 2

72 + [ 62 - (102 - 4.16)]

= 72 + [ 62 - (102 - 64)]

= 72 + [62 - 38]

= 72 + 24 

= 96 

Answer 3

7²+ {6²-(10²-4.16)}

=49+{36-(100-64)}

=49+(36-36)

=49+0

=49
