​

Answer 1

Answer:

18.7959184

Step-by-step explanation:

take π=22/7

take π=22/7then substitute,

take π=22/7then substitute, i.e., = 2×22/7 -5×{22/7}²+17

take π=22/7then substitute, i.e., = 2×22/7 -5×{22/7}²+17then, = 44/7 - 220/49 + 17

take π=22/7then substitute, i.e., = 2×22/7 -5×{22/7}²+17then, = 44/7 - 220/49 + 17 = 44/7 × 7/7 -220/49 + 17 × 49/49

take π=22/7then substitute, i.e., = 2×22/7 -5×{22/7}²+17then, = 44/7 - 220/49 + 17 = 44/7 × 7/7 -220/49 + 17 × 49/49 = 308/49 - 220/49 + 833/49

take π=22/7then substitute, i.e., = 2×22/7 -5×{22/7}²+17then, = 44/7 - 220/49 + 17 = 44/7 × 7/7 -220/49 + 17 × 49/49 = 308/49 - 220/49 + 833/49 = (308 - 220 + 833) ÷ 49

= 18.7959184
