Can be expressed as the quotient of two integers ie a fraction with a denominator that is not zero many people are surprised to know that a repeating decimal is a rational number.
													
																	Square root of 200 rational or irrational. 
									
	
		
	
																	But the 5th root of 33 is irrational. 
																	It is an irrational number if it is not a perfect square. 
																	Thus the square root of 28 is irrational. 
																	The square root of 28 is the same as the 2 x the square root of 7. 
															
													
									
	
		
	
																	The square roots of some numbers are rational. 
																	200 is rational generally a number is rational unless it involves roots like square root cube root ect or is a special number like pi an irrational number is a number that cannot be. 
																	31 √1000 32. 
																	Let s start out with the basic inequality 961 1000 1024. 
															
													
									
	
		
	
																	33 is not a perfect 5th power. 
																	Now we ll take the square root of this inequality. 
																	The square root of 300 is irrational. 
																	D square root of 3 5 e 2 3 in the same way we saw that only the square roots of square numbers are rational we could prove that only the nth roots of nth powers are rational. 
															
													
									
	
		
	
																	7 is prime and so the square root of 7 is irrational. 
																	It s irrational here s the proof. 
																	The square root of 200 is a rational number if 200 is a perfect square. 
																	Since 200 is not a perfect square it is an irrational number. 
															
													
									
	
		
	
																	Thus the 5th root of 32 is rational because 32 is a 5th power namely the 5th power of 2. 
																	Eg sqrt 4 2 sqrt 0 04 0 2 sqrt 400 20 the square roots of some numbers are irrational eg sqrt 2 1 414 approx sqrt 0 02 0 1414.
