√x = x^( 1/2).?
For any non-zero positive integer, we can definitely decompose it into the product of at least two integers (expressed as x 1, x2, x3 ...).
x^( 1/2)=(x 1)^( 1/2)(x2)^( 1/2)...(xn)^( 1/2)
Where x=x 1*x2*x3*x4...*xn.
As you are only in junior high school, the above items can't exceed three at most, that is, x (1/2) = (x1) (1/2) (x2) (1/2).
For example:
√ 12 =? √(4x3) = √4*√3 = 2√3
√3 is approximately equal to 1.732, so √12 = 2x1.732 = 3.464.
√ 18 =? √(9x2) =? √9x√2 = 3√2
√2 is approximately equal to 1.4 14, so √18 = 3x1.414 = 4.242.
Pay attention to several common root number results that need to be memorized.
Extended reading:
Reciting list of common root symbols:
√2 is approximately equal to 1.4 14.
√3 is about 1.732.
√5 is approximately equal to 2.236.
6 is about 2.449.
√7 is approximately equal to 2.646.
