<h3>What are the
simplified mathematical expressions ?</h3>
Scientific notation is used to simplify large numbers in smaller numbers. In order to write a number in scientific notation , the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
(8.6 x
) . (9.1 x
)
= (8.6 x 9.1) x
= 78.26 x
= 7.8 x 10
(6.9 x
) . (4.8 x
)
= 33.12 x 
3.3 x 
(3.7 x
) . (4.6 x
) ÷ (1.4 x
) . (5.7 x
)
= 1.7 x 10 ÷ 8 x10²
0.21 x 
2.1 x 
(3.1 x
) . (5.3 x
) ÷ (7.3 x
) . (6.1 x
) = 3.7

To find a number in between you could multiply 39/130 by 2/2
and 40/130 by 2/2 to get
78/260 and 80/260
The standard equation of circle when center is (h,k) and radius is 'r'

h = 2 and k = - 5, radius = 16
So equation of the circle is given by
