What is scientific notation?
Scientific notation is defined as a way of expressing numbers which are too large or too small so that they can be easily written in decimal form. It can be referred to the scientific form or the scientific index form or even the standard form.
Base ten notation is used by scientists, engineers as it helps in simplification of arithmetic operations. It contains the significant figures which include all non-zero numbers , the zeroes between significant digits and zeroes which are needed to be significant.
In scientific notation, the base should always be ten. The exponent should be a non-zero integer and it can be either positive or negative.
For example , in the given problem 6.0×10^4=60,000 and 4.0×10^8=40,00,00,000
∴60,000÷40,00,00,000=0.00015 which in scientific notation is expressed as 1.5×10[tex]^-4[/tex]
