Question

(a) The number 25 can be written in scientific notation as
2. Fill in the blanks.​

Answer 1

Answer:

hey mate here is your answer.

Your number in decimal form is 0.25 . To get to "standard" scientific notation, we move the decimal point so there is only one non-zero digit in front of the decimal point. So, 0.25 becomes 02.5 . The leading zero is not significant, so 02.5 becomes 2.5 .

Answer 2

$\huge \mathfrak \orange{answer}$

The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.

Calculating scientific notation for a positive integer is simple, as it always follows this notation:

a x 10b

Follow the steps below to see how 25 is written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 25

New Number: 2.5

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 2 . 5

Decimal Count: 1

There are 1 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 2.5

b = 1

Now the whole thing:

2.5 x 101

Step 4

Check your work:

101 = 10 x 2.5 = 25
