What is 403,000,000,000,000 in scientific
notation?
(A) 4.03 x 1014
(B) 403 x 1014
(C) 4.03 × 10 -14
(D) 40.3 x 1014

(A) 4.03 x 10^14

Step-by-step explanation:

403,000,000,000,000

Scientific notation is of the form

a * 10 ^b

where a is a number from 1 to a number less than 10

Put the decimal in the number

403,000,000,000,000.

We need to move the decimal 14 places to the left to get the number to be between 1 and 10

4.03000000000000  so the b is 14

Since we moved it to the left b is positive

We can drop the extra zeros at the end (after the last nonzero digit)

4.03 *10^14

A

Step-by-step explanation:

4.03 × 10¹⁴

14 digits after 4. So power is 14

step-by-step explanation:

a² + b²= c²

24² + 7² = c²

c= 25
