How do you simplify this expression
raketka [301]
Convert <span>6\frac{3}{8}<span>6<span><span>​8</span>​<span>​3</span><span>​​</span></span></span></span><span> to improper fraction. Use this rule: </span><span>a \frac{b}{c}=\frac{ac+b}{c}<span>a<span><span>​c</span>​<span>​b</span><span>​​</span></span>=<span><span>​c</span>​<span>​<span>ac+b</span></span>​​:</span></span></span>
​∣8<span><span>​<span>​<span>6×8+3</span></span><span>​​</span></span>−2∣+∣−8<span><span>​8</span>​<span>​5</span><span>​​</span></span>−1<span>∣


</span></span>Simplify <span>6\times 8<span>6×8</span></span><span> to </span>48: <span><span><span><span><span>
​</span>8</span>​<span>​<span>48+3</span></span><span>​​</span></span>−2∣+∣−8<span><span>​8</span>​<span>​5</span><span>​​</span></span>−1∣


</span>Simplify <span>48+3<span>48+3</span></span><span> to </span>51:</span><span><span><span><span><span>
​</span>8</span>​<span>​<span>51</span></span><span>​​</span></span>−2∣+∣−8<span><span>​8</span>​<span>​5</span><span>​​</span></span>−1∣

</span> Make the denominators the same:
<span><span><span>51</span><span>​​/8</span></span>−2×<span><span>​8</span>​<span>​8</span><span>​​

</span></span></span><span>Simplify. Denominators are now the same:
</span>
<span><span><span>51</span><span>​​/8</span></span>−<span><span>​8</span>​<span>​<span>16</span></span><span>​​
</span>
</span></span>Join the denominators: \frac{51-16}{8}<span><span>​8</span>​<span>​<span>51−16</span></span><span>​​
</span>
etc.. and your answer will be 14

What is the principal or(postive)square root of a number N
Margaret [11]
The square root of number n is a number, r, that when squared equals n.
Each positive number has two square roots, a positive one and a negative one. The principal square root of a positive number is the positive square root.

For example, this of n = 4.
There are two numbers, r, that when squared equal 4.
The are 2 and -2, since 2^2 = 4 and (-2)^2 = 4.
4 has two square roots, a positive one and a negative one.
The positive square root, 2, is the principal square root of 4.

The symbol for the principal square root is the square root symbol.

\sqrt{4}

means the principal square root of 4, which is 2.

If you mean the negative square root of 4, which is -2, then you must write a negative sign before the square root symbol.

-\sqrt{4}

means the negative square root of 4 which is -2.
