Find the mistake in these mathematical equations. x = 2 x(x-1) = 2(x-1) x2-x = 2x-2 x2-2x = x-2 x(x-2) = x-2 x = 1
Find the mistake in the below maths equations
A = 2 A(A-1) = 2(A-1) A2-A = 2A-2 A2-2A = A-2 A(A-2) = A-2 A = 1
Using mathematical symbols like +, -, and x in order to make the equations correct. Replace # with the above-given symbols.
9 # 8 # 7 # 6 # 5 # 4 = 91
Find the value of all these with the help of the equations below. If Pastry + Icecream + Pizza + Donut = 24 Pastry + Donut = Icecream Pizza - Donut = 2 Pastry + Pastry - 1 = Icecream Then Pastry = ? Pizza = ? Icecream = ? Donut = ?
The following is my attempt at proving that 1<-1 . In which of these steps did I first make a mistake? Step 1: Let i = sqrt(-1) then i^2 = -1 and i^4=1. Step 2: Hence, we have i^2 < i^4 Step 3: We divide both sides by i to get i < i^3. Step 4: We divide both sides by i again to get 1<i^2 or 1 < -1
