Question

(5 + 2)2 − 40 + 3

Answer 1

(5 + 2)2 − 40 + 3

Answer 2

Exponents come first by default. Spacing means nothing in mathematics.

40 - 2^33^2 / 6 + 5
40 - 4^33 / 6 + 5

I will round 4^33 for simplicity.

40 - (7.38 x 10^19)/ 6 + 5
40 - 1.23 x 10^19 + 5

Which is essentially

-1.23 x 10^19

Answer 4

(5+2)^2 -40 +3
=25+4-40+3
