Answer 6

The product of 9√3 ⋅6√7 is 54√21.

Answer 7

To multiply √11 by 6√7, you simply multiply the coefficients and multiply the square roots.

6√7 × √11 = 6 × √(7 × 11) = 6√77.

Therefore, the exact answer is 6√77.

Answer 8

To divide 2√65 by √5, we rationalize the denominator by multiplying the numerator and denominator by √5.

(2√65) / (√5) = (2√65 * √5) / (√5 * √5) = 2√(65 * 5) / 5 = 2√(325) / 5 = (2/5)√(325).

Therefore, the exact answer is (2/5)√325.

Answer 9

To divide 9√33 by 27√11, we can simplify the expression by cancelling out common factors.

First, we can simplify the coefficients (numbers in front of the square roots):
9/27 = 1/3.

Next, we can simplify the square roots:
√33/√11 = √(33/11) = √3.

Combining the simplified coefficient and square root, we get the exact answer:
(1/3)√3.

Answer 10

I apologize for the mistake. Let's correct the division:

To divide 9√33 by 27√11, we multiply both the numerator and denominator by the conjugate of the denominator, which is √11.

(9√33)/(27√11) * (√11)/(√11) = (9√33 * √11) / (27 * √11 * √11) = (9√(33*11))/(27*11) = (9√363)/(297)

However, √363 is not a perfect square, so we cannot simplify it further. Therefore, the exact answer is:

(9√363)/(297)

Answer 11

To simplify √99, we can break down 99 into its prime factors: 99 = 3 * 3 * 11.

Now we can simplify the square root:
√99 = √(3 * 3 * 11) = √(3^2 * 11) = 3√11.

Therefore, 7√99 simplifies to 7 * 3√11 = 21√11.
