the standard form of a 5 digit number is a*10^m and a 4 digit number is m*10^n what is the standard form of the number (m*n) * 10^m+n
Answers
Step-by-step explanation:
Scientific notation is a way of expressing real numbers that are too large or too small to be conveniently written in decimal form. It may be referred to as scientific form or standard index form, or standard form in the UK. This base ten notation is commonly used by scientists, mathematicians, and engineers, in part because it can simplify certain arithmetic operations. On scientific calculators it is usually known as "SCI" display mode.

In scientific notation, all numbers are written in the form
m × 10n
or m times ten raised to the power of n, where the exponent n is an integer, and the coefficient m is any real number. The integer n is called the order of magnitude and the real number m is called the significand or mantissa.[1] However, the term "mantissa" may cause confusion because it is the name of the fractional part of the common logarithm. If the significand is negative then a minus sign precedes m, as in ordinary decimal notation. In normalized notation, the exponent is chosen so that the absolute value (modulus) of the significand m is at least 1 but less than 10.
Decimal floating point is a computer arithmetic system closely related to scientific notation.
