Question

find the exponential form of the following


a) 462 b) 3986 c) 120x400

Answer 1

Answer:

s we discussed earlier that it involves a number of the numerical terms expressed in exponents. Let us take the example of the number 1000.

We can write 1000 as 10x10x10, but instead of writing 10 three times we can write the number 1000 in an alternative way too.

1000 = 10 x 10 x 10

1000 =  (10)3………..(exponential form)

Let us take another example to further clarify the concept of expressing a number in exponential form.

Let us take the example of a number 576895.

Now we can express this number in the following ways

576895 = 5×100000 + 7×10000 + 6×1000 + 8×100 + 9×10 + 5×1

576895= 5 x 105 + 7×104 + 6×103 + 8×102 + 9×101 + 5x 100

The last term which includes 100 can simply be written as 1 because any number when expressed raising it to the power of 0 it equals 1.

Therefore we can clearly say that exponents simply refer to how many times a particular number appears in a numerical term.
