To express the given expression in scientific notation, we first add the numbers:
1.9 × 10^3 + 8.7 × 10^3
Next, we can combine the terms and rewrite the expression as:
(1.9 + 8.7) × 10^3
Simplifying the expression within the parentheses:
10.6 × 10^3
Finally, we can write the answer in scientific notation by combining the coefficient (10.6) and the power of 10 (3):
1.06 × 10^4
To evaluate and express the answer in scientific notation, we add the numbers first and then adjust the decimal point and exponent if necessary.
1.9 × 10^3 + 8.7 × 10^3
Adding the numbers:
1.9 + 8.7 = 10.6
Now, adjust the decimal point:
10.6 becomes 1.06 by moving the decimal point one place to the left.
Finally, adjust the exponent:
10^3 becomes 10^4 by increasing the exponent by one.
So, the answer in scientific notation is 1.06 × 10^4.
To evaluate the expression "1.9 times 10 cubed plus 8.7 times 10 cubed" and express the answer in scientific notation, you need to add the two numbers together and then rewrite the result in scientific notation.
First, add the two numbers:
1.9 times 10 cubed + 8.7 times 10 cubed = (1.9 + 8.7) times 10 cubed
= 10.6 times 10 cubed
Note that when adding or subtracting numbers in scientific notation, you need to make sure the exponents are the same.
Next, rewrite the result in scientific notation:
10.6 times 10 cubed = 1.06 times 10 times 10 cubed
= 1.06 times 10 to the power of (3+1)
= 1.06 times 10 to the power of 4
Therefore, the answer to the expression in scientific notation is 1.06×10^4.
