Which radical expression is an irrational number? A. √ 121 B. √ 65 C. √ 36 D. √ 64

alina1380 [7]

We will verify each options

option-A:

$\sqrt{121}$

we can factor it

$\sqrt{121}=\sqrt{11*11}$

$\sqrt{121}=\sqrt{11^2}$

$\sqrt{121}=11$

so, this is not irrational.........Answer

option-B:

$\sqrt{65}$

Since, it can not be factored

so, this is irrational.........................Answer

option-C:

$\sqrt{36}$

we can factor it

$\sqrt{36}=\sqrt{6*6}$

$\sqrt{36}=\sqrt{6^2}$

$\sqrt{36}=6$

so, this is not irrational.........Answer

option-D:

$\sqrt{64}$

we can factor it

$\sqrt{64}=\sqrt{8*8}$

$\sqrt{64}=\sqrt{8^2}$

$\sqrt{64}=8$

Steps to solve a two step equation

Kobotan [32]

I'm not entirely sure about some of these because there could be multiple answers, i think. i'll just leave the ones i can't help you with blank.

1) Begin to (isolate) the (variable) by eliminating the (constant). To eliminate the constant, you want to make it (cancel?) because ___+___=___)
2) (Balance) your equation by doing the exact same thing in the opisite side of the (equal sign).
3) Finish (isolating) the (variable) by eliminating the (coefficient). To eliminate the coefficient, you want to make it (cancel?) because ___x___=___,
4) (Balance) your equation by doing the exact same thing on the opposite side of the (equal sign).
5) Check your answer by (plugging) it in or the _____.

honestly, i find it really amusing that they found a way to break a TWO-step equation into 5 steps ?? but i hope this helps a little!!
