Answer 1

Hi ,

( 5 - 2 × 10 - 4 ) / ( 2 - 5 × 5 - 6 )

= ( 5 - 20 - 4 )/( 2 - 25 - 6 )

= ( -15 - 4 )/( -23 - 6 )

= ( -19 )/ ( - 29 )

Answer 2

The value of (5-2 x 10-4) / (2-5 x 5-6) is 0.656

Solution:

We have to find value of (5-2 x 10-4) / (2-5 x 5-6)

Let use BODMAS rule

According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right.

First we multiply the numbers

$\frac{(5-2 \times 10-4)}{(2-5 \times 5-6)}$

Now we add the negative integers

$\frac{(5-20-4)}{(2-25-6)}$

Now we subtract the obtained numbers

$\begin{array}{c}{\frac{(5-24)}{(2-31)}} \\\\ {\frac{(-19)}{(-29)}}\end{array}$

On cancelling the negative sign we get

$\frac{(19)}{(29)}=0.656$

Thus the value of given expression is 0.656
