Multiply and write it in scientific notation.
(8*10^3)*(7*10^5)
A.5.6*10^16
B.5.6*10^9
C.1.5*10^16
D.1.5*10^9
Is the answer A? I really don't know how to do scientific notationđŸ˜±
When multiplying/dividing, exponents are added/subtracted respectively.
Answer is not A.
To multiply numbers in scientific notation, you multiply the coefficients and add the exponents.
In this case, you have:
(8 * 10^3) * (7 * 10^5)
Multiplying the coefficients, 8 * 7 equals 56.
Adding the exponents, 10^3 * 10^5 equals 10^(3+5) which simplifies to 10^8.
Therefore, the result is 56 * 10^8.
Now, we can write this in scientific notation by moving the decimal point one place to the left, which makes the coefficient 5.6, and using the exponent 10^8.
So, the answer is 5.6 * 10^8.
Therefore, the answer is not A (5.6 * 10^16), but rather, the answer is B (5.6 * 10^8).
