The value of the expression for the given values of a and b is -1

<h3>Evaluating an expression</h3>

From the question, we are to evaluate the given expression for the given values of a, b, and c

The given expression is

a + b

The given values are

a = 4,

b = -5,

and

c = -8

To evaluate the given expression for the given values of a and b, we will put the values of a and b into the expression,

That is,

a + b becomes

4 + -5

= 4 -5

= -1

Hence, the value of the expression for the given values of a and b is -1

The number 12,300 is written ______. as a coefficient in standard form in scientific notation

dexar [7]

The number 12,300 is written 1.23 x 10⁴ as a scientific notation. It's coefficient is 1.23; base is 10⁴ in exponent form.

Scientific notation is a method developed by scientists to shorten the number that expresses a very large number. The scientific notation is based on powers of the base number 10.

Scientific notation has two numbers: coefficient and base. The coefficient must be greater than or equal to 1 and less than 10. The base is always 10 written in exponent form.

12,300 as coefficient in standard form in scientific notation.

1) put decimal after the first digit and drop the zeros. from 12,300 to 1.23 this is the coefficient.

2) to find the exponent, count the number of places from decimal to the end of the number.
1.2300 ; there are 4 places

So the scientific notation is 1.23 x 10⁴
