Question

Answer 1

  

Answer 2

`82 - 6.(9-2^3) + 11`

`= 82 - 6.(9-8)+11`

`= 82 - 6.1 + 11`

`= 82 - 6 + 11`

`= 76 + 11`

`= 87`

__________________________________________

`9.(8^2 - 15) : 7 - 10.6`

`= 9.(64 - 15) : 7 - 60`

`= 9.49 : 7 - 60`

`= 441 : 7 - 60`

`= 63 - 60`

`= 3`

__________________________________________

`3^8 : 3^5 + 2015^0 - (100 - 95)^2`

`= 3^3 + 1 - 5^2`

`= 27 + 1 - 25`

`= 28 - 25`

`= 3`

Answer 3

d)82-6.(9-2³)+11
=82-6.(9-8)+11
=82-6.1+11
=82-6+11
=87
h)9.(8²-15):7-10.6
=9.(64-15):7-10.6
=9.49:7-60
=63-60
=3
n)3⁸:3⁵+2015⁰-(100-95)²
=6561:243+1-25
=27+1-25
=3
