Question

Write each number in standard form 62 hundreds and 30 tens

Answer 1

i) 6.2 x
`10^(3)`

ii) 3 x
`10^(2)`

Explanation:

We are given two numbers 62 hundreds and 30 tens.

We need to write them in standard form.

Any number can be written in standard form.

Standard form = a x
`10^b` where 1 ≤ a <10 and b should be an integer.

62 hundreds = 62 *100 = 6200 this is a normal form.

Standard form

62 houndreds = 62 *
`10^(2)` = 6.2 x
`10^(3)`

[In 62, we moved 1 decimal point left because "a" must be less than 10. So we add 1 to the power existing 10's power (2 +1)]

30 tens = 30*10 = 300. This is a normal form

In 30, we move 1 decimal point to the left, so we add 1 with 10's power when we write in standard form.

30 tens = 30*10 = 3 x
`10^(2)`

Answer 2

We are given : 62 hundreds and 30 tens .

To find : the number in standard form.

Soltuion: We know hundreds represents times 100.

Also tens reprents times 10.

In order to find the values of 62 hundreds, we need to multiply 62 by 100.

In order to find the values of 32 tens, we need to multiply 32 by 10.

62 × 100 = 6200

32 × 10 = 320.

Now, we need to add those numbers above.

6200 + 320 = 6520.

In simple, we could also show as

62 hundreds and 30 tens = 62 × 100 = 30 × 10 = 6200+300 = 6520.

Therefore, standard form is 6520.
