What is the value of (5.3x10^4)(4.2x10^3)l
Alenkinab [10]

Answer:

scientific notation = 2.226 * 10^8

Standard form = 222600000

As it is 22.26 * 10^7

Step-by-step explanation:

(5.3x10^4)(4.2x10^3)

Since all the numbers are being multiplied by each other, one can use the associative property to change the order in which they are multiplied.

5.3 x 10^4 x 4.2 x 10^3

= 5.3 * 4.2 * 10^4 * 10^3

= 22.26 * 10^7

Either convert back to scientific notation, standard form or keep as it is.

scientific notation = 2.226 * 10^8

Standard form = 222600000

As it is 22.26 * 10^7

Please help!! I'm very confused
Tom [10]

Answer:

b+7

Step-by-step explanation:

To simplify an equation, you combine like terms and remove redundancies. Like terms are 4b and 3b, another pair of like terms are 9 and 2. Let's combine them. 4-3 is 1, so we can make the equation into 1b+9-2. We can simplify that to b+9-2. But wait, we can combine 9 and 2. 9-2 is 7, so the final simplified equation is b+7. I hope this helps!
