Multiply 9√3 x 6√7. Give an exact answer.

Answer 1

To multiply, we multiply the numbers outside the square roots and multiply the numbers inside the square roots separately.

9√3 × 6√7 = (9 × 6) × (√3 × √7)
= 54 × √(3 × 7)
= 54 × √21

So, the exact answer is 54√21.

Answer 2

√11 x 6√7

Answer 3

To multiply, we multiply the numbers outside the square roots and multiply the numbers inside the square roots separately.

√11 × 6√7 = (√11 × 6) × (√7)
= 6√(11 × 7)
= 6√77

So, the exact answer is 6√77.

Answer 4

divide 2√65/√5

Answer 5

To divide, we can simplify the expression by rationalizing the denominator.

2√65 / √5 = (2√65 / √5) * (√5 / √5)
= (2√65 * √5) / (√5 * √5)
= (2√(65 * 5)) / √(5 * 5)
= (2√325) / √25
= (2√325) / 5

So, the simplified form of 2√65 / √5 is (2√325) / 5.

Answer 6

divide 2√65/√5 provide an exact answer

Answer 7

To divide, we can simplify the expression by rationalizing the denominator.

2√65 / √5 = (2√65 / √5) * (√5 / √5)
= (2√65 * √5) / (√5 * √5)
= (2√(65 * 5)) / (√(5 * 5))
= (2√325) / √25
= (2√(5 * 5 * 13)) / (5)
= (2 * 5 * √13) / 5
= 10√13 / 5
= 2√13

So, the exact answer of 2√65 / √5 is 2√13.

Answer 8

divide 9√33 / 27√11

Answer 9

To divide, we can simplify the expression by rationalizing the denominator.

9√33 / 27√11 = (9√33 / 27√11) * (√11 / √11)
= (9√33 * √11) / (√11 * √11)
= (9√(33 * 11)) / (√(11 * 11))
= (9√363) / √121
= (9√(3 * 11 * 11)) / 11
= (9 * 11 * √3) / 11
= 9√3

So, the exact answer of 9√33 / 27√11 is 9√3.

Answer 10

simplify 7√99

Answer 11

To simplify √99, we need to find the largest perfect square that goes into 99. The largest perfect square that goes into 99 is 9, since 9 * 11 = 99.

√99 = √(9 * 11) = √9 * √11 = 3√11

Therefore, 7√99 simplifies to 7 * 3√11, which is equal to 21√11.
