The value of a2+b2 = 0.05
The value of a3+b3 = 41.73
Concept: (a+b)2 = a2+b2+2ab
(a-b)2 = a2+b2-2ab
(a+b)3 = a3+b3+3a2b+3ab2
(a-b)3 = a3-b3-3a2b+3ab2
(I) a²+b²=(1/7-4✓3)²+(1/7+4✓3)²
⇒ ( 1/49 - 48) +(1/49 + 48)=(1-2352/49) + (1+2353/49)
⇒ -47.97 +48.02= 0.05
(ii) a³+b³=(1/7-4✓3)³+(1/7+4✓3)³
⇒(-6.78)³ +(7.07)³
⇒-311.66 +353.39= 41.73

Step-by-step explanation:
wow
1.25s+y=t
a= fair admission
1.25s=amount spent on tickets for rides
t=total
Example
1.25*25+y=t
31.25+y=43.75
y=12.50
If you multiply the price of the ride tickets by the amount bought then subtract it from the amount spent total you get the admission price. You can use this equation for anyone who only pays for the rides and fair admission
