Explanation

Step 1

break the parenthesis:

to do that, multiply the signs,

$\begin{gathered} -\cdot-=\text{ +} \\ so \end{gathered}$ $\begin{gathered} -\frac{1}{2}-(-\frac{3}{4}) \\ -\frac{1}{2}-(-\frac{3}{4})=-\frac{1}{2}+\frac{3}{4} \\ -\frac{1}{2}+\frac{3}{4} \end{gathered}$

Step 2

now, add / subtract the fractions:

remember.

$\frac{a}{b}\pm\frac{c}{d}=\frac{ad\pm bc}{bd}$

$\begin{gathered} -\frac{1}{2}+\frac{3}{4} \\ \frac{3}{4}-\frac{1}{2}=\frac{3\cdot2-1\cdot4}{4\cdot2}=\frac{6-4}{8}=\frac{2}{8}=\frac{1}{4} \\ -\frac{1}{2}+\frac{3}{4}=\frac{1}{4} \end{gathered}$

therefore,

$\begin{gathered} -\frac{1}{2}-(-\frac{3}{4})=\frac{1}{4} \\ \end{gathered}$

so,the answer is

$\frac{1}{4}$

I hope this helps you

What is the remainder of (2^91 x 6^27) divided by 7?

kondaur [170]

$2\equiv2\mod7$
$2^2\equiv4\mod7$
$2^3\equiv8\equiv1\mod7$

$91=3(30)+1$
$\implies2^{91}\equiv(2^3)^{30}\times2^1\equiv1^{30}\times2\equiv2\mod7$

$6\equiv-1\mod7$
$6^2=6\times6\equiv6(-1)\equiv-6\equiv1\mod7$

$27=2(13)+1$
$\implies6^{27}\equiv(6^2)^{13}\times6^1\equiv1^{13}\times6\equiv6\mod7$

$\implies2^{91}\times6^{27}\equiv2\times6\equiv12\equiv5\mod7$
