Question

how do u write 3.98×10^6 in a decimal form

Answer 1

Answer:

Given number is 3.98 x 10⁶

If the exponent is positive then the decimal point ' . ' moves to the right otherwise it goes to left side.

The first zero next to the decimal point indicates Ones, the second zero is Tens, the third zero is Hundreds, the fourth zero is Thounds, the eight is Ten thousands, the nine is Hundred thousand and the three is Thousand thousands.

Simple understaning is the sum of the all these terms gives the same number.

3000000+900000+80000+000+00+0 = 3980000
