Answer 1

a) 2^3 + 45:3^2 = 8 + 15:9 = 23:9 = 2.56

b) 6 x 2^2 + 7^0 x 2^1 = 24 + 2 = 26

c) 3^2 x 10^3 - 20^2 = 9 x 1000 - 400 = 9000 - 400 = 8600

d) 6^2 + 3^2 = 36 + 9 = 45

f) 3^3 : 9 = 27 : 9 = 3

g) 7^0 + 0^7 = 1 + 0 = 1

h) (6^2 - 5^2) : 11 = (36 - 25) : 11 = 11 : 11 = 1

i) 2 + 3 x 5 + 3^4 = 2 + 15 + 81 = 98

j) (2^4 - 3 x 5^1) : 1 = (16 - 15) : 1 = 1

k) 2023^0 + 300 : 100 = 1 + 300 : 100 = 301 : 100 = 3.01
