Question

5.2³ - 2.3² + 90:10

Answer 1

31

Answer 2

5 . 2³ - 2 . 3² + 90 : 10

= 2 . (5 . 2² - 3²) + 90 : 10

= 2 . (5 . 4 - 9) + 90 : 10

= 2 . (20 - 9) + 90 : 10

= 2 . 11 + 90 : 10

= 22 + 9

= 31

Answer 3

5.2^{3 _} 2.3² + 90:10

=5.8-2.9+90:10

=40-18+9=31

Answer 4

5.2³ - 2.3² + 90:10

=5.8 - 2.9 + 9

=40 - 18 + 9

=22+9

=31

Answer 5

\(5.2^3-2.3^2+90:10\)

\(=5.8-2.9+9\)

\(=40-18+9\)

\(=31\)
