please hep me to solve these simple question

Answer:
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
