Answer:
3√7
Step-by-step explanation:
(√3)(√21) = √(3·21) = √(3·3·7) = √(3²·7) = 3√7
__
The product of the roots is the root of the product. The product, 3·21 = 63, has a square factor that can be removed from under the radical. You need to factor out the root of that square when you simplify the expression.
x = 3 - (3×6) + 2. We perform the operation in the bracket first.
x = 3 - 18 + 2
x = -15 + 2 = 2 -15 = -13
x = -13
Answer:
$3.3
