Question

standard form of 3890000​

Answer 1

3890000 = 3.89 × 10⁶

Given :

The number 3890000

To find :

To express in standard form

Concept :

For any given number Standard form is a way to express the number .

It is generally used to express a large or a small number

The standard form of any given number is

$\sf = m\times {10}^{n}$

Where m is a number such that 1 ≤ m < 10 and n is the exponent of 10

Solution :

Step 1 of 2 :

Write down the given number

Here the given number is 3890000

Step 2 of 2 :

Express in standard form

$\displaystyle \sf{ 3890000 }$

$\displaystyle \sf{ = 389 \times 10000 }$

$\displaystyle \sf{ = 389 \times {10}^{4} }$

$\displaystyle \sf{ = 3.89 \times {10}^{2} \times {10}^{4} }$

$\displaystyle \sf{ = 3.89 \times {10}^{2 + 4} }$

$\displaystyle \sf{ = 3.89 \times {10}^{6} }$

Hence the required standard form of 3890000 is 3.89 × 10⁶
