Simplify square root of 8y/share root of y

lozanna [386]

Answer:

$2\sqrt{2}$

Step-by-step explanation:

We are required to simplify the following expression;

$\frac{\sqrt{8y} }{\sqrt{y} }$

Using the properties of radicals;

$\frac{\sqrt{a} }{\sqrt{b}}=\sqrt{\frac{a}{b} }$

The expression can be re-written as;

$\sqrt{\frac{8y}{y}}=\sqrt{8}$

Now;

$\sqrt{8}=\sqrt{4*2}=\sqrt{4}*\sqrt{2}\\ \\2\sqrt{2}$

Show your work and hurry please

spayn [35]

Answer:

Step-by-step explanation:

Note: Take note , absolute value will give the magnitude of the value. (Which means ignoring the + / - signs.)

Eg. | - 19 | = 19

Therefore,

$\frac{12(30 - (9 + {4}^{2})) }{10 - | - 6| } \\ = \frac{12(30 - (9 + 16))}{10 - 6} \\ = \frac{12(30 - 25)}{4} \\ = \frac{12(5)}{4} \\ = \frac{60}{4} \\ = 15$
