Ineed this asap. 1. what's the coefficient of the term ab2? . 2. implify by using the order of operations. 4(3 – 7)2 + 102. 3. evaluate the expression, if possible: √49/25

Answer (1):

Coefficient of any term  means the number multiplied in that term including sign.

is same as .

Hence required coefficient is 1.

Answer (2):

Hence final answer is 166

Answer (3):

Hence final answer is

1. Coefficient is 1

2. 166

3. or

Step-by-step explanation:

1. Since there is no number mentioned before the term therefore its coefficient is 1.

2.

Using the order of operations, we will start by solving in the brackets first to get:

3.

SInce both the numerator and the denominator are under the square root so we can write them as:

is an improper fraction so we can write it in mixed form as
