Find the missing term.

igor_vitrenko [27]

Equations are used to relate equal expressions.

The missing term is: $\mathbf{ m -1}$

The equation is given as:

$\mathbf{\frac{m - n}{m^2 - n^2} + \frac{?}{(m -1)(m -n)} = \frac{2m}{m^2 - n^2}}$

Express $\mathbf{m^2 - n^2\ as\ (m - n)(m + n)}$

So, we have:

$\mathbf{\frac{m - n}{(m - n)(m + n)} + \frac{?}{(m -1)(m -n)} = \frac{2m}{(m - n)(m + n)}}$

Multiply through by $\mathbf{m - n}$

$\mathbf{\frac{m - n}{m + n} + \frac{?}{m -1} = \frac{2m}{m + n}}$

Collect like terms

$\mathbf{ \frac{?}{m -1} = \frac{2m}{m + n} - \frac{m - n}{m + n}}$

Take LCM

$\mathbf{ \frac{?}{m -1} = \frac{2m - m + n}{m + n} }$

$\mathbf{ \frac{?}{m -1} = \frac{m + n}{m + n} }$

Divide $\mathbf{ \frac{m + n}{m + n} }$

$\mathbf{ \frac{?}{m -1} = 1}$

Cross multiply

$\mathbf{ ? =(m -1)\times 1}$

$\mathbf{ ? =m -1}$

Hence, the missing term is: $\mathbf{ m -1}$

Let s be the sum of all digits used in writing all numbers from 1 to 1010.find s

Sophie [7]

We know, s = n/2 [a + l ]
Here, n = 1010
a = 1
l = 1010

Substitute their values,
s = 1010/2 [1 + 1010]
s = 505 [ 1011]
s = 510555

In short, Your Answer would be 5,10,555

Hope this helps!
