Toshi and owen need to add 4.9 x 10^9 and 4.1 x 10^7. toshi says they must use the expression (490 x 10^7 ) (4.1 x 10^7), but owen says they must use the expression (4.9 x 10^9) (0.041 x 10^9). are neither, one, or both students correct? explain

Answers

Final answer:

When adding numbers in scientific notation, the exponents must be the same. Owen is correct and Toshi is incorrect.

Explanation:

Explanation:

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.

Which expression forms an equation with the given expression?8 • 7 – 4 = ___________
(Points : 1)
(2 + 9) • 2
10 • 3 – 6
9 • 5 + 7
9(12 ÷ 2)

Answers

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.

The answer is 9*5+7
9*5=45 +7=52
