Given:

\sqrt{2}=1.414

To find:

The value of \sqrt{50}+\sqrt{72}.

Solution:

We have,

\sqrt{50}+\sqrt{72}

It can be rewritten as

=\sqrt{2\times 25}+\sqrt{2\times 36}

=\sqrt{2}\times \sqrt{25}+\sqrt{2}\times \sqrt{36}        [\because \sqrt{ab}=\sqrt{a}\sqrt{b}]

=5\sqrt{2}+6\sqrt{2}

=11\sqrt{2}

Putting \sqrt{2}=1.414, we get

=11(1.414)

=15.554

Therefore, the value of given expression is 15.554.

How do i solve x/8=3/4
dusya [7]

Answer:

Quite simply. The answer is X=6

Since you have a full fraction, you can find a common denominator in both fractions and multiply. (The common denominator would be 8, so you would multiply 4 by 2 to get 8. Do the same thing to the top, do multiply 3 by 2 to get 6). Now the fraction is 6/8, and since it's equal to incomplete fraction, you know X is 6.

Ik this is late, but people who are looking for the answer can see this.

Answer:

an =1/3*6^n-1

Step-by-step explanation:

You should plug in 2 for n in each equation, which, the correct one should give you 2. Then, to make sure, you plug in 3 in the equations that gave you 2.

Example:

an = 1/3 * 6 ^n-1

Plug in 2.

an = 1/3 * 6 ^2-1

an = 1/3 * 6 ^1

1/3 * 6 = 2

Step 2.

an = 1/3 * 6 ^3-1

an = 1/3 * 6 ^2

1/3 * 36 = 12

Hope this helps.
