Question

Answer this and get 100 points

which number below is equivalent to the product

A 7.2 * 10 by the power 9
B 7.2 * 10 by the power 11
C. 7.2 * 10 BY THE POWER 23
D 7.2* 10 BY THE POWER 25

Answer 1

B. 7.2*10 by power 11

Since

`= 8 * 9 * {10}^(4) * {10}^(6)`

`= 72 * {10}^(4 + 6)`

`= 72 * {10}^(10)`

`= 7.2 * {10}^(1) * {10}^(10)`

`= 7.2 * {10}^(1 + 10)`

`= 7.2 * {10}^(11)`

Hence 7.2*10 by power 11 is equivalent to the product.

Answer 2

B

Explanation:

The product of (8 * (10^6)) * (9 * (10^4)) can be calculated as follows:

(8 * (10^6)) * (9 * (10^4)) = 8 * 9 * (10^6) * (10^4) = 72 * (10^(6+4)) = 72 * (10^10)

So the equivalent number is 7.2 * 10^11, which is option B.
