Answer:
[tex]5\times10^{11}[/tex]
Step-by-step explanation:
In order to get the answer to this question you will have to put the scientific notations into their number form then multiply, then change back into scientific notation form.
[tex](2.5\times10^8)\times(2\times10^3)[/tex]
Turn the notations into their number form:
[tex]2.5\times10^8[/tex]
The exponent is positive so move the decimal point to the right:
[tex]2.5\times10^8=250000000[/tex]
Do the same with the second notation:
[tex]2\times10^3[/tex]
Since the exponent is positive move the decimal point to the right:
[tex]2\times10^3=2000[/tex]
Now multiply:
[tex]250000000 \times 2000 = 500000000000[/tex]
Now turn the number into scientific notation:
[tex]500000000000 = 5.0\times10^{11}[/tex]
[tex]=5\times10^{11}[/tex]
Hope this helps.
