Verify $a - (- b) = a + b$ for $a = 131, b = 15$ .

Open in App

Solution

Given $a = 131$ and $b = 15$ .
Now, $a - (- b) = 131 - (- 15) = 131 + 15 = 146$ and $a + b = 131 + 15 = 146$ .
So, $a - (- b) = a + b$ .

(\frac{2}{5} a^{2} b) \times (- 15 b^{2} a c) \times (- \frac{1}{2} c^{2})

(a + b)^{2} - (a - b)^{2} = 4 a b

a = 4, b = 3

a^{3} + b^{3} = (a + b)^{3} - 3 a b (a + b)

a = 3, b = 4

A = [\begin{matrix} 2 & 1 & 3 \\ 4 & 1 & 0 \end{matrix}], B = [\begin{matrix} 1 & - 1 \\ 0 & 2 \\ 5 & 0 \end{matrix}]

A = [\begin{matrix} 1 & 3 \\ 2 & 4 \end{matrix}], B = [\begin{matrix} 1 & 4 \\ 2 & 5 \end{matrix}]

A \subset B

A = {{a, b, c}}, B = {1, {a, b, c}, 2}
