Please hep me to solve these simple question

Step-by-step explanation:

a

(9-2)² + 16/8

= 7² + 2

= 49 + 2

= 51

b

(81/9) * (3/2)⁵

= 9 * (3⁵/2⁵)

= 9 * 243/32

= 2187/32

= 2176/32 + 11/32

= 68 + 11/32

= 68 11/32

c

(8 + 5*5) - (36/6)²

= (8 + 25) - 6²

= 33 - 36

= -3

d

4*(95/5) - 8 * (9-2)²

= 4*19 - 8*7²

= 76 - 8*49

= 76 - 392

= -316
