Question

How many times greater is 8.5x10^8 than 42x10^7 in scientific notation

Answer 1

To find out how many times greater 8.5x10^8 is than 42x10^7 in scientific notation, we can divide one number by the other. The result is 0.20238 x 10^1, so 8.5x10^8 is approximately 0.20238 times greater than 42x10^7.

Step-by-step explanation:

To find out how many times greater 8.5x10^8 is than 42x10^7 in scientific notation, we can divide one number by the other. In this case, we divide 8.5x10^8 by 42x10^7:

(8.5x10^8) / (42x10^7) = 8.5 / 42 x 10^(8-7) = 0.20238 x 10^1.

So, 8.5x10^8 is approximately 0.20238 times greater than 42x10^7 in scientific notation.

Answer 2

Step-by-step explanation:

first, let's bring them to the same exponent of 10.

8.5 × 10⁸ is already scientific notation

42 × 10⁷ = 4.2 × 10⁸ (this is now scientific notation AND it is using the same exponent of 10)

so, how many times is the first one greater ?

(8.5 × 10⁸) / (4.2 × 10⁸) = 8.5 / 4.2 = 2.023809524...

so, the first number is 2.023809524... times greater than the second number.

maybe you made a typo ?

maybe the second number was actually 42.5 × 10⁷ ?

because then

42.5 × 10⁷ = 4.25 × 10⁸

and

8.5 / 4.25 = 2

so,

8.5 × 10⁸ is 2 times greater than 42.5 × 10⁷ or 4.25 × 10⁸.
