simplify sqrt((-1)^2+(-1)^2)

simplify

(- 1)^{2} + (- 1)^{2}

2

Solution steps

(- 1)^{2} + (- 1)^{2}

Add similar elements:

(- 1)^{2} + (- 1)^{2} = 2 (- 1)^{2}

= 2 (- 1)^{2}

Apply exponent rule:

(- a)^{n} = a^{n},

n

is even

(- 1)^{2} = 1^{2}

= 2 \cdot 1^{2}

1^{2} = 1

= 2 \cdot 1

Multiply the numbers:

2 \cdot 1 = 2

= 2

\frac{12 x - 3 y}{15 a + 10 b} \cdot \frac{21 a + 14 b}{20 x - 5 y}

1 \frac{1}{2} \cdot 3

- 1 + 6 x - 8 x + 4 - 2 x

\frac{y + 2}{( y + 2 ) ^{2}} \cdot \frac{y ^{2} - 4}{y}

\frac{( x ^{2} + 2 x )}{x}
