When adding numbers in scientific notation, the exponents must be the same. Owen is correct and Toshi is incorrect.
When adding numbers in scientific notation, the exponents must be the same.
Toshi suggests using the expression (490 × 10⁷) + (4.1 × 10⁷), but this is incorrect because the exponents do not match.
Owen suggests using the expression (4.9 × 10⁹) + (0.041 × 10⁹), and this is correct because the exponents are the same.
So, Owen is correct and Toshi is incorrect.

10 • 3 – 6
9 • 5 + 7
9(12 ÷ 2)
Answer:
8 • 7 – 4 = 9 • 5 - 7.
Step-by-step explanation:
Given : 8 • 7 – 4 = ___________
To find : Which expression forms an equation with the given expression.
Solution : We have given 8 • 7 – 4 = ___________
First we solve the product
56 - 4.
52
Now we will check the 9 • 5 + 7
Solve the product 45 + 7 = 52.
So, the 8 • 7 – 4 = 9 • 5 - 7
Therefore, 8 • 7 – 4 = 9 • 5 - 7.
Answer:
56 as a decimal is 56.0 :)
Step-by-step explanation:
A whole number is a number whose fraction part is zero. To convert a whole number into a decimal, you must decide the result to a certain number of places after the decimal point and simply add a decimal and the number of zeros required to the right side of the whole number.
