You know how decimals are really long to write, like 0.00000000089? Well, with scientific notation, you can shorten them. Take the decimal I wrote for instance. Using scientific notation, I can change it to 8.9 * 10^-10. The decimal is shortened, and according to the exponent, 10^-10, we move the decimal place for 8.9 to the left ten places, leaving us with 0.00000000089.
you mean : 5/8x + 1/16x = 5/16 +x
<=> 10/16x +1/16x = (5 +16x)/16
(16x # 0)
<=> 11/16x = x(5+16x)/(16x)
<=>11 = x(5+16x)
<=> 11 = 16x^2 + 5x
<=> x =-1 or x =11/16
