Question

The Earth's circumference measured at the equator is approximately 1.3148 × 108 feet. What is the number written in standard form?

Answer 1

Answer:

The number written in standard form is $131,480,000$

Step-by-step explanation:

we have

$1.3148*10^8$

we know that

$10^8=100,000,000$

substitute

$1.3148*10^8=1.3148(100,000,000)$

Remember that

When multiplying decimals by 10, move the decimal point one space to the right

In this case move the decimal point eight spaces to the right

$1.3148(100,000,000)=131,480,000$

therefore

The number written in standard form is $131,480,000$
