Answer:
The solution is x = 3
Step-by-step explanation:
Hi there!
First, let´s write the equation:
log(3) + 2 log(x) = log(27)
Substract log(3) from both sides of the equation
2 log(x) = log(27) - log(3)
Apply logarithm property: log(a) -log(b) = log(a/b)
2 log(x) = log(27/3)
2 log(x) = log(9)
Apply logarithm property: log(xᵃ) = a log(x)
log(x²) = log(9)
Apply logarithm equality rule: if log(a) = log(b) then a = b
x² = 9
Apply square root to both sides of the equation
x = 3
The solution is x = 3
Have a nice day!
Answer:
(a) 4.00×10^7 m
(b) 5.10×10^14 m^2
(c) 1.083×10^21 m^3
Step-by-step explanation:
Put the given value of radius into the various formulas and do the arithmetic. Your scientific calculator can show you the results in scientific notation.
C = 2πr = 2π·6.37×10^6 m ≈ 4.00×10^7 m* . . . circumference
A = 4πr^2 = 4π(6.37×10^6 m)^2 ≈ 5.10×10^14 m^2 . . . area
V = (4/3)πr^3 = (4/3)π(6.37×10^6 m)^3 ≈ 1.083×10^21 m^3 . . . volume
