You have to use the order of operations when evaluating algebraic expressions. The mnemonic device is PEMDAS, which stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. So the first thing is to solve what's in the parentheses.

Answer:

When evaluating an algebraic expression the first thing you do is that you observe what would be the first operation applied on the expression.

In order to determine that you need to know the basic concept of PEMDAS

Where as

P stands for Parentheses (brackets)

E stands for exponents

M stands for multiplication

D stands for division

A stands for addition

S stands for subtraction

This is the order that needs to be kept in mind while solving the expression

Answer:

Option B
Option C
Option E

Explanation:

Option B is true because both of the terms are constants. Hence, they are like terms.
Option C is true because the coefficient of a term is basically the constant. If there is no constant, then the coefficient is 1.
Option E is true because the expression has been multiplied by 5.

Answer:

1. A. 1

2. D. $17^9$

Step-by-step explanation:

Properties used:

Power of a Power Property
Product Property
Quotient Property
Zero Exponent Property

1. First, let's deal with the numerator.

$(17^3)^6$ can be turned into $17^1^8$ by using the Power of a Power Property.

And then use the Product Property, $(17^1^8)(17^-^1^0) = 17^8$

So now, our fraction is this: $\frac{17^8}{17^8}$

All number over itself in a fraction is equal to 1. But you can also do this the mathmatic way using the Quotient Property: $\frac{a^m}{a^n} = a^m^-^n$ or $\frac{1}{a^(^n^-^m^)}$ . Which then you plug the numbers in: $\frac{17^8}{17^8} = 17^8^-^8 = 17^0$ . And since we know that in Zero Exponent Property: $a^0 = 1$ , we can see that $17^0 = 1$ . So either way, we get 1.
