Show that 5-√3 is irrational

WebIf the square root is a perfect square, then it would be a rational number. On the other side, if the square root of the number is not perfect, it will be an irrational number. i.e., √10 = 3.16227766017. Examples: References: Roberts, D. Rational, and Irrational Numbers - MathBitsNotebook (A1 - CCSS Math). WebAnswer (1 of 3): How can you prove that 3 - 5 3√ is an irrational number? Let 3–5√3 be a rational number and let it be p/q such that p and q are integers and they are not sharing any common factor i. e. they are co-prime integers. 3–5√3 = p/q, therefore ——- I 3–p/q = 5√3, therefore ——- II (3 ...

WebOr if you have an irrational that is sqrt5 (to the third root) raised to the third power, the 1/3 and 3 will cancel each other when you multiply the 3 and 1/3 to each other and it will become 5, a rational number. Or, for instance, sqrt 5 times sqrt 5, both are irrational, but when you multiply them together, you get sqrt 25, which is 5.
