Answer 2

Answer:

Step-by-step explanation:

1.3×100=1.3

in standard form.

Explanation:

In scientific notation, we write a number so that it has single digit to the left of decimal sign and is multiplied by an integer power of

10.

In other words, in scientific notation, a number is written as

a ×10n, where 1≤a<10 and n is an integer and 1≤a< 10.To write the number in normal or standard notation one just needs to multiply by the power

10n(or divide if n is negative). This means moving decimal

n digits to right if multiplying by

10n and moving decimal n digits to left if dividing by 10n

(i.e. multiplying by 10−n).

In the given case, as we have the number as

1.3×100, we need not move decimal digit to either side and hence in standard notation  1.3×100=1.3  itself.
