Question 1:

For this case we have that by definition, the GCF of two numbers is the largest number that is a factor of both numbers. For example, the number 10 is the biggest factor that 50 and 30 have in common.

We must find the GCF of the following expression:

30t ^ 2u + 12tu ^ 2 + 24tu

We look for the prime factorization of each number:

30: 2 * 3 * 5\\12: 2 * 2 * 3\\24: 2 * 2 * 2 * 3

The GCF of the three numbers is 2 * 3 = 6

So:

6tu (5t + 2u + 4)

Answer:

Option C

Question 2:

For this case we have that by definition of power properties of the same base, that:

a ^ n * a ^ m = a ^ {n + m}

That is, for multiplication of powers of the same base, the same base is placed and the exponents are added.

So:

b ^ n * b ^ m = b ^ {n + m}

ANswer:

b ^ {n + m}

Option A

180 = 89+42+x

180-89-42=x

49 = x

2nd box

180 = 84+58+x

180-84-58=x

38 = x

3rd box

180=74+2x

180-74=2x

106/2 = x

53 = x

4th box

180=102+2x

180-102=2x

78/2 = x

39 = x

4th box

180 = 73+81 +x

180-73-81=x

26 = x

5th box

180=2*54+x

180 - 2*54 = x

72 = x

6th box

180=62-2x

180-62=2x

118=2x

118/2=x

59 = x

7th box

180 = 2*68 + x

180-2*68=x

44 = x
