A would be the closest estimate
To<span> find a </span>power of a product, look the power of each factor and then multiply. If you want to multiply two powers with the same exponent but different bases, you use the commutative property of multiplication. Product of powers property shows us that when you multiply powers with the same base you just have to add the exponents. This is raising a <span>power to a power.</span>
So the answer should be 48.58 if not then it could be 278n
B: Apply the distributive property to get 4x - 12=9
