To find 1251/3 we have to solve x3 = 125 => This gives x=5 Then we have 2-3 is equal to 1/(23) => This is equal to 1/8So to answer the question we have 5*...
factorise x3+2x2+x=0 => x(x2+2x+1)=0 => x(x+1)(x+1)=0 => x(x+1)2=0 => This leads to x=0 and (x+1)2=0 so x=0 and x+1=0 => Giving us the...
The following function consists of the sum of two variables x^n and x^3 * sin(1/[3x]). Let's break the differentiation down term by term and differentiate xn first since it's the easier term. R...
(x+a)(x+b) = 0The two numbers must have a product of 12 and a sum of 7.3*4 = 12 AND 3+4=7Therefore(x+3)(x+4) = 0Therefore x+3 = 0 --> x = -3OR x+4 = 0 --> x = -4
The first step to writing an expression with more than one fraction as a single fraction is to find their lowest common denominator. For example, in a question with two fractions where the denominators ar...
