Simplify the following surds
a) 18
b) 12
c) 32
Will mark brainliest answer ​

Answers

Answer:

___________________________________________________________

FACTS TO KNOW BEFORE SOLVING :-

To simplify a surd , ensure that the number is expressed in such a way that it is the product of factors.Try to express the number as the product of 2 or more perfect squares (if any) because it makes the process of simplifying the surd easier.

___________________________________________________________

According to the question ,

a) [tex]\sqrt{18} =\sqrt{9 \times 2} = \sqrt{9} \times \sqrt{2} = 3\sqrt{2}[/tex]

b) [tex]\sqrt{12} =\sqrt{4 \times 3} = \sqrt{4} \times \sqrt{3} = 2\sqrt{3}[/tex]

c) [tex]\sqrt{32} = \sqrt{16 \times 2} = \sqrt{16} \times \sqrt{2} = 4\sqrt{2}[/tex]

9. Combine the radical expression, if possible.

Answers

Answer:

we conclude that:

[tex]3\sqrt{125}+4\sqrt{20}=23\sqrt{5}[/tex]    

Hence, the last option i.e. [tex]23\sqrt{5}[/tex] is correct.                      

Step-by-step explanation:

Given the expression

[tex]3\sqrt{125}+4\sqrt{20}[/tex]

Combining the radical expressions

[tex]3\sqrt{125}+4\sqrt{20}[/tex]

let us first solve

[tex]3\sqrt{125}[/tex]

[tex]=3\sqrt{5^3}[/tex]

[tex]=3\sqrt{5^2\cdot \:5}[/tex]

Apply radical rule:  [tex]\sqrt{ab}=\sqrt{a}\sqrt{b},\:\quad \:a\ge 0,\:b\ge 0[/tex]

[tex]=3\sqrt{5^2}\sqrt{5}[/tex]

Apply radical rule:   [tex]\sqrt{a^2}=a,\:\quad \:a\ge 0[/tex]

[tex]=3\cdot \:5\sqrt{5}[/tex]

[tex]=15\sqrt{5}[/tex]

Thus,

[tex]3\sqrt{125}=15\sqrt{5}[/tex]

similarly solving

[tex]4\sqrt{20}[/tex]

[tex]=4\sqrt{2^2\cdot \:5}[/tex]

Apply radical rule:  [tex]\sqrt{ab}=\sqrt{a}\sqrt{b},\:\quad \:a\ge 0,\:b\ge 0[/tex]

[tex]=4\sqrt{2^2}\sqrt{5}[/tex]

Apply radical rule:   [tex]\sqrt{a^2}=a,\:\quad \:a\ge 0[/tex]

[tex]=4\cdot \:2\sqrt{5}[/tex]

[tex]=8\sqrt{5}[/tex]

Thus,

[tex]4\sqrt{20}=8\sqrt{5}[/tex]

so we get

[tex]3\sqrt{125}=15\sqrt{5}[/tex]

[tex]4\sqrt{20}=8\sqrt{5}[/tex]

so the expression becomes

[tex]3\sqrt{125}+4\sqrt{20}=15\sqrt{5}+8\sqrt{5}[/tex]        ∵ [tex]3\sqrt{125}=15\sqrt{5}[/tex] , [tex]4\sqrt{20}=8\sqrt{5}[/tex]

                        [tex]=23\sqrt{5}[/tex]                   ∵ [tex]15\sqrt{5}+8\sqrt{5}=23\sqrt{5}[/tex]

Therefore, we conclude that:

[tex]3\sqrt{125}+4\sqrt{20}=23\sqrt{5}[/tex]    

Hence, the last option i.e. [tex]23\sqrt{5}[/tex] is correct.

If 3 – 5x = 2, then x =

Answers

3-5x=2

or, x= 1/5

The value of x is 1/5 for equation 3 – 5x = 2

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equation is 3 – 5x = 2

Three minus five times of x equal to two

We need to solve for x

3 – 5x = 2

Subtract 3 from both sides

3-3-5x=2-3

-5x=-1

Divide both sides by -5

x=-1/-5

x equal to one by five

x=1/5

Hence, the value of x is 1/5 for equation 3 – 5x = 2
