Answer: 1
<u>Step-by-step explanation:</u>
a + b = 1
a³ + b³ = (a + b)(a² - ab + b²) <em>formula for a perfect cube</em>
a³ + b³ + 3ab = (a + b)(a² - ab + b²) + 3ab
↓
= 1 (a² - ab + b²) + 3ab
= a² - ab + b² + 3ab
= a² + 2ab + b² <em>this is a perfect square</em>
= (a + b)(a + b)
↓ ↓
= (1) (1)
= 1
Answer:
B = log₃243 = 5
Step-by-step explanation:
By using the rule of aⁿ = b ==> logₐb = n, you can transform the exponent form into a logarithmic form by switching around the values of each letter to their desired place. It is interchangable between the two equations.
