 Hello and welcome to the session. Today I will help you with the following question. The question says express the following number in usual form. Let's move on to the solution. The number given to us is 5.8 multiplied by 10 to the power 12. That is this is equal to 5.8 multiplied by 12 times 0. As there are 12 zeros in the numerator, so we will move this decimal of 5.8 12 places to the right. This is one move 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 and so we will place the decimal here. Thus this becomes equal to 5.8 0, 0, 0, 0, 0, 0, 0, 0, 0, 0. This is the usual form. Hence our final answer is 5.8 0, 0, 0, 0, 0, 0, 0, 0. So hope you enjoyed the session. Have a good day.
