x=\frac{5,6\times 10^{1}\times 2,25}{3\times 10^{8}}
To multiply powers of the same base, add their exponents. Add -7 and 8 to get 1.
x=\frac{2,25\times 5,6}{3\times 10^{7}}
Cancel out 10 in both numerator and denominator.
x=\frac{12,6}{3\times 10^{7}}
Multiply 2,25 and 5,6 to get 12,6.
x=\frac{12,6}{3\times 10000000}
Calculate 10 to the power of 7 and get 10000000.
x=\frac{12,6}{30000000}
Multiply 3 and 10000000 to get 30000000.
x=\frac{126}{300000000}
Expand \frac{12,6}{30000000} by multiplying both numerator and the denominator by 10.
x=\frac{21}{50000000}
