√(25 - 10 √(3) + 3) (not as a decimal)

nikitadnepr [17]

Answer:

$\huge\boxed{\sqrt{25-10\sqrt3+3}=5-\sqrt3}$

Step-by-step explanation:

$\sqrt{25-10\sqrt3+3}=(*)\\\\25=5^2\\3=(\sqrt3)^2\\10\sqrt3=(2)(5)(\sqrt3)\\\\(*)=\sqrt{5^2-(2)(5)(\sqrt3)+(\sqrt3)^2}\\\\\text{use}\ (a-b)^2=a^2-2ab+b^2\\\\=\sqrt{(5-\sqrt3)^2}\\\\\text{use}\ \sqrt{a^2}=|a|\\\\=|5-\sqrt3|=5-\sqrt3\\\\^{\text{because}\ 5>\sqrt3\to5-\sqrt3>0}$

3. What is the distributive property of 40 + 64?

Ivan

Answer:

104

Step-by-step explanation:

This is not a distributive property question though.

A distributive property has a number (a) outside the parenthesis

a(b+c)

so in this case a(40+64)

then you would multiply a by both numbers

40a+64a

then add them together

104a

However if it is a number outside the parenthesis and not a variable, it will come out different

For example

5(40+64)

(5*40)+(5*64)

200+320

520

Hope this helps!
