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.
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.
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.
