Prove that 3 2 sqrt5 is irrational - Given: $3 + 2sqrt{5}$To do: Here we have to prove that $3 + 2sqrt{5}$ is an irrational number.Solution:Let us assume, to the contrary, that $3 + 2sqrt{5}$ is rational.So, we can find integers a and b ($≠$ 0) such t
I can give you an example and prove it: eg. take the rational no. 2...hence its additive inverse ie. its opposite no. will be -2 now lets add: =(2)+(-2) =2-2 =0 it means that the opposite no.s. get cancelled and give the answer 0 this is the ...
Step 2: Square both sidesNext, we square both sides of the equation to eliminate the square root:5=A2B2 Step 3: Cross-multiplyNow, we cross-multiply to get rid of the fraction:5B2=A2 Step 4: Analyze the equationFrom the equation 5B2=A2, we can see that A2 is divisible by 5. Thi...
