Add 7.3x10^7+1.8x10^7 . What is the sum? (Use scientific notion)
The sum of 7.3x10^7 and 1.8x10^7 is 9.1x10^7.
3.4x10^6+1.3x10^5 . What is the sum using scientific notions?
The sum of 3.4x10^6 and 1.3x10^5 is 3.53x10^6.
3.45x10^6+1.3x10^5 . What is the sum using scientific notions?
The sum of 3.45x10^6 and 1.3x10^5 is 3.58x10^6.
2.8x10^5+15,300 . What is the sum in scientific notion?
To represent the sum in scientific notation, we first need to rewrite 15,300 in scientific notation. 15,300 can be written as 1.53x10^4.
Now, we can add 2.8x10^5 and 1.53x10^4:
2.8x10^5 + 1.53x10^4 = 2.8x10^5 + 0.153x10^5
Next, we can add the coefficients (2.8 + 0.153) and keep the same base (10) raised to the power of 5:
2.8x10^5 + 0.153x10^5 = 2.953x10^5
Therefore, the sum in scientific notation is 2.953x10^5.
Add 1.28x10^11+384,000,000,000 . What is the sum in scientific notion?
In order to add 1.28x10^11 and 384,000,000,000, we first need to write 384,000,000,000 in scientific notation.
384,000,000,000 can be written as 3.84x10^11.
Now we can add 1.28x10^11 and 3.84x10^11:
1.28x10^11 + 3.84x10^11 = (1.28 + 3.84)x10^11
Next, we can add the coefficients (1.28 + 3.84) and keep the same base (10) raised to the power of 11:
1.28x10^11 + 3.84x10^11 = 5.12x10^11
Therefore, the sum in scientific notation is 5.12x10^11.
To find the sum of 7.3x10^7 and 1.8x10^7 in scientific notation, you first need to make sure that the exponents (the powers of 10) are the same. In this case, both numbers have an exponent of 7.
To add the two numbers:
1. Add the coefficients (the numbers multiplied by the powers of 10): 7.3 + 1.8 = 9.1.
2. Keep the common exponent: 10^7.
The sum in scientific notation is 9.1x10^7.
