Question

7,618,272,763km^2 in scientific notation to two digits after the decimal

Answer 1

In scientific notation we use powers of 10

first we need to count how many ciphers or numbers have the question

there are 10 numbers here

So we have 0.7618 x 10^10

BUT the problem says two digits after decimal, so we need to add two ZEROS after the decimal then it gives

0.007618 x 10^ 10 , and multiply this by 10^2

so then multiplying same base 10^10x (10^2)= 10^12

and the final result is

0.007618 x 10^12
