#*******(a) solution*****************

a = 2.3
numerator = 6*a+42
denomenoterspower = 4.2-3.62
denomenoter = 3^denomenoterspower
print(numerator/denomenoter)
if(numerator/denomenoter==29.50556)
print(“Verified”)
#***********(b) solution************
negative4 = -4
squarenegative4 =negative4^2
#**********check for option i)
a = (-4)^2+2
print(“Option a is correct”)
#**********check for option ii)
b = -4^2+2
print(“Option b is correct”)
#**********check for option iii)
c = (-4)^(2+2)
print(“Option a is correct”)
#**********check for option iv)
d = -4^(2+2)
print(“Option a is correct”)

#*******(c) solution
avg = (25.2+15+16.44+15.3+18.6)/5
print(sqrt(avg/2.0))

#****(d) soution****
#log(x, base = exp(1))
#x is number and base is base of the log
#exp(1) = e ie base of the log is e
print(log(0.3, base = exp(1)))

#*****(e) solution
#exp function find exponential
print(exp(log(0.3, base = exp(1))))

#*****(f)solution
num = -0.00000000423546322
print(‘R representation when printing on console’)
print(num)
