Which of the following statements are true? Check all that apply For all real numbers a and b, a b b+ a For all real numbers a a
nd b, ab ba. For all real numbers a and b, a b a For all real numbers a and b For all real numbers a, and c, (a b) c a (b c) b For all real numbers a, b and c, (a b) c a (b-c For all real numbers a, b and c, a b c) ab ac
The correct answer for the question that is being presented above is this one: "(1) <span>For all real numbers a and b, a + b = b+ a; </span>(2) For all real numbers a and b, ab = ba; (3) <span>For all real numbers a, b and c, (a + b) + c = a + (b + c); (4) </span><span>For all real numbers a, b and c, a (b + c) = ab + ac." </span>
When making two logarithms one logarithm you keep the base (in this case that would be 2) and multiply the two numbers (in this case 7 times 6 = 42) so the answer is
