Count the number of digits after the first digit. this gives you the exponent on the 10. The first number in scientific form has the decimal point after the first digit.
For mercury there are 7 digits after the 5:-
So the Mercury answer is
5.7909175 * 10^7
Follow this procedure for the other planets
The answer for Venus is
1.08208930 * 10^8
2x + 5y=10 .........equation 1
2x + 3y=6 .........equation 2
subtracting eq 2 from eq 1 we get
2y =4
y=2
putting y=2 in eq 1
we get
x=0
