Simple Square Root of Junior Middle School Mathematics Lesson 1
1. Find the square root of the following number.

36 1

Square root = number of soil roots 36 1= soil 19.

Absolute values of-1 and 1 1/9.

Square root = number of soil roots |-20/9|= number of soil roots 2/3 5

2+ 14/25

Square root = TugenNo. (2+ 14/25)= Tu8/5。

Second, find the following values.

√324= 18

√ 3 2+4 2 = soil 5

-√ 1^2-7/ 16

=-root number 9/ 16

=-3/4

Third, find X in the following formula.

x^2+ 1= 145

x^2= 144

X= soil 12

8(x+ 1)^2-50=0

(x+ 1)^2=25/4

X+ 1= 5/2 of soil.

x 1=- 1+5/2=3/2

x2=- 1-5/2=-7/2
