To multiply 0.75 by 2.8x10^-5, you can either multiply the decimal numbers as usual or convert them to scientific notation.
Decimal multiplication:
0.75 x 2.8x10^-5 = 0.021x10^-5 = 2.1x10^-4
Therefore, the answer is 2.1x10^-4.
To multiply 0.75 by 2.8×10−5, you can multiply the decimal numbers and then adjust the power of 10.
0.75 × 2.8 = 2.1
Now, adjust the power of 10:
10−5 × 10−2 = 10−5+(-2) = 10−7
So, the final answer is 2.1×10−7.
To multiply 0.75 by 2.8×10−5, you can follow these steps:
Step 1: Multiply the decimal numbers, 0.75 and 2.8.
0.75 * 2.8 = 2.1
