What is coefficients?

A coefficient is a number or quantity that is associated with a variable. Typically, it is an integer multiplied by the variable and written next to it. The variables which do not have a number with them are assumed to be having 1 as their coefficient. For example, 3 is the coefficient of x in the expression 3x, but 1 is the coefficient of x2 in the expression x2 + 3. A coefficient, in other words, is a multiplicative factor in terms of a polynomial, a series, or any expression. Consider the following expression, which shows that 5 is the x2 coefficient and 8 is the y coefficient.

The moon has a circumference of about 10,920,000 meters. Give the circumference of the moon in scientific notation

Anit [1.1K]

Answer:

$1.092*10^{7}\ m$

Step-by-step explanation:

we know that

$10,920,000\ m=(1.092)*10,000,000\ m$

$10,000,000=10^{7}$

substitute

$10,920,000\ m=1.092*10^{7}\ m$

To simplify a radical, look for a factor that is a perfect square. Radicals and multiplying are very friendly to each other and you can separate the "radicand" (the inside number) into factors inside the radical also into separate radicals to simplify. See image
