Question

1024:2⁶+160:(3³+53)-9¹⁰⁰:9⁹⁹

Answer 1

`1024:2^6 +160:(3^3 +53)-9^100 :9^99`

`=2^10 :2^6 +160:(27+53)-9^(100-99)`

`=2^(10-6)+160:80-9^1`

`=2^4 +2-9`

`=16+2-9`

`=18-9`

`=9`

Answer 2

\(1024:2^6+160:\left(3^3+53\right)-9^{100}:9^{99}\)

\(=2^{10}:2^6+160:\left(27+53\right)-9^{100-99}\)

\(=2^{10-6}+160:80-9\)

\(=2^4+2-9\)

\(=16+2-9\)

\(=9\)

Answer 3

2^10:2^8+160:(26+53)-9

2^4+160:80-9

16+2-9

9
