What is equivalent to 3 radical 8

klemol [59]

Answer:

Equivalent $3\sqrt{8}=6\sqrt{2}$

Step-by-step explanation:

Given: 3 radical 8

Mathematically 3 radical 8 can be written as $3\sqrt{8}$

We have to find an equivalent to $3\sqrt{8}$ .

Given expression can be written as ,

$3\sqrt{8}=3\sqrt{4 \times 2}$

On further simplification, we get,

$3\sqrt{4 \times 2}=3(\sqrt{4} \sqrt{2} )$

We know $\sqrt{4}=2$

further simplification gives,

$3\sqrt{8}=6\sqrt{2}$

Thus, Equivalent $3\sqrt{8}=6\sqrt{2}$

Reuben says, "two days ago i was 20 years old. later next year, i will be 23 years old." how is this possible?

Aneli [31]

Let us always base on the present age. We denote this by x. Now, the age he had 2 years ago would then be denoted as (x-2). Let's equate this to 20 years old.

x - 2 = 20
x = 20 + 2
x = 22 years old
He should be 22 years old now.

Let's check the other condition. After 1 year, his age should be (x+1). Let's equate this to 23 years old.

x + 1 = 23
x = 23 - 1
x = 22

Thus, this is possible if Reuben is 22 years old as of the present.
