How will you write 1 billion using exponent?
1 billion can be written as 1,000,000,000 or represented as 109 . How would 2 billion be represented? Since 2 billion is 2 times 1 billion, then 2 billion can be written as 2×109 2 × 10 9 .
What is 1000000000 as a power of 10?
| Powers of 10 | |
|---|---|
| 101=10 | 101=1 |
| 107=10,000,000 (ten million) | 10-6=0.000001 (one millionth) |
| 108=100,000,000 (one hundred million) | 10-7=0.0000001 (one ten millionth) |
| 109=1,000,000,000 (one billion) | 10-8=0.00000001 (one hundred millionth) |
How do you calculate negative exponents?
A negative exponent is defined as the multiplicative inverse of the base, raised to the power which is opposite to the given power. In simple words, we write the reciprocal of the number and then solve it like positive exponents. For example, (2/3)-2 can be written as (3/2)2.
What does it mean when the exponent is negative?
The larger the negative exponent, the smaller the number it represents. While positive exponents indicate repeated multiplication, negative exponents represent repeated division. That’s why 2-3 is greater than 2-6.
What is a number to the power of negative 1?
Negative one is a special value for an exponent, because taking a number to the power of negative one gives its reciprocal: x−1=1x.
How do you do negative exponents with negative numbers?
How to solve negative exponents. Flip the base and exponent into the reciprocal, then solve the denominator. Divide the numerator by the denominator to find the final decimal.
What does a negative exponent mean?
A positive exponent tells us how many times to multiply a base number, and a negative exponent tells us how many times to divide a base number. We can rewrite negative exponents like x⁻ⁿ as 1 / xⁿ.
How do you visualize a billion?
Writing big numbers can take a lot of space. If you write a 1 followed by nine zeros, you get 1,000,000,000 = one billion!
