Question

Evaluate the expression

3 + 4 x 5^1

26 - 4^2 ÷ 5^1

( 3^3 - 2^4 ) x 5

20 - ( 5 - 2)^2 + 2 x 3

Answer 1

7. 23

8. 18

9. 55

10. 17

Explanation:

Answer 2

3+4 x 5^1
7 x 5^1
=35

26-4^2 / 5^1
22^2 / 5^1
484 / 5
= 96.8

(3^3 - 2^4) x 5
(37 - 16) x 5
21 x 5
= 105

20 - (5 - 2)^2 + 2 x 3
20 - (3)^2 + 2 x 3
20 - 9 + 2 x 3
20 - 9 + 6
20 - 15
=5
