Question

Write the number 7.5x10^-2 in standard form

Answer 1

Explanation:

To write the number 7.5x10^-2 in standard form, we can convert it to decimal notation.

Step 1: Take the number 7.5.

Step 2: Move the decimal point two places to the left since the exponent is -2. This gives us 0.075.

Step 3: Express the number without any exponents. Therefore, the standard form of 7.5x10^-2 is 0.075.

In standard form, we express numbers without using scientific notation or exponents.

Answer 2

0.075

Explanation:

Definition of standard form:

Standard form is a way of writing numbers that is commonly used in science and mathematics. In standard form, the number is written as a product of a number between 1 and 10 and a power of 10.

Converting
`\sf 7.5* 10^(-2)` to standard form:

In order to convert to standard form, we need to move the decimal point two places to the left.

This is because the exponent of 10 is negative.

`\sf 7.5* 10^(-2) = 0.075`

Therefore, the number in standard form is 0.075.
