Simplify square root of 3 times square root of 21

Answers

Step-by-step explanation: To multiply the square root of 3 times the square root of 21, we simply multiply the numbers that are inside the square roots together.

So, root 21 × root 3 equals root 63.

Next, we simplify the square root of 63. 63 factors as 3 x 21 and 21 factors as 3 x 7. So we have a pair of 3's which means a 3 can come out of the radical and the 7 doesn't pair up stays in the radical so our final answer is $\sqrt[3]{7}$ .

3√7 is the simplified value of the given expression.

To simplify the expression √3 * √21, we can combine the square roots and simplify under one radical if possible.

√3 * √21 = √(3 * 21)

Simplifying the product inside the radical:

√(3 * 21) = √63

Now, we can simplify further by factoring 63 into its prime factors:

√(3 * 21) = √(3 * 3 * 7)

Taking the square root of each factor:

√(3 * 3 * 7) = √3 * √3 * √7 = 3 * √7

Therefore, √3 * √21 simplifies to 3√7.

Round to the given place: 256,035 (thousands)

Answers

So,

When rounding to the nearest thousand, look at the number in the hundreds place. If it is greater than or equal to 5, round up. If not, round down.

256,035

The hundreds place is less than 5, so we round down.

256,035 --> 256,000

256,000. The 6 is in the thousandths place, and since the 0 in the hundredths place is less than 5, you do not round up, keeping the 256,000 as opposed to 257,000.

What is the simplified form of the equation fraction 4 over 5 n minus fraction 1 over 5 equals fraction 2 over 5 n?n = −2
n = 4
n = fraction 1 over 2
n = fraction 2 over 3

Answers

Answer: The correct option is

(C) n = fraction 1 over 2.

Step-by-step explanation: We are to find the simplified form of the fraction 4 over 5 n minus fraction 1 over 5 equals fraction 2 over 5 n.

From the given information, we can write the equation as follows:

$(4)/(5)n-(1)/(5)=(2)/(5)n.$

Solving the above equation, we get

$(4)/(5)n-(1)/(5)=(2)/(5)n\n\n\n\Rightarrow (4)/(5)n-(2)/(5)n=(1)/(5)\n\n\n\Rightarrow (4-2)/(5)n=(1)/(5)\n\n\n\Rightarrow (2)/(5)n=(1)/(5)\n\n\n\Rightarrow n=(5)/(2* 5)\n\n\n\Rightarrow n=(1)/(2).$

Thus, the required simplified form is $n=(1)/(2).$

Option (C) is CORRECT.

4/5n – 1/5 = 2/5n
Add 1/5 to both sides
4/5n = 2/5n + 1/5
Subtract 2/5n from both sides
2/5n = 1/5
Divide both sides by 2/5
