pashok25 [27]4 years ago

Answer:

x=2

Step-by-step explanation:

6^x^10  = 6^12^2 / 6^4

We know a^b^c = a^(b*c)

6^ 10x = 6^(12*2) / 6^4

6^ 10x = 6^(24) / 6^4

We know a^b / a^c = a^(b-c)

6^ 10x = 6^(24 -4)

6^ 10x = 6^(20)

Since the bases are the same, the exponents are the same

10x = 20

Divide each side by 10

10x/10 = 20/10

x=2

Liono4ka [1.6K]

Answer:

<u>There are 70 students on the two buses, 42 on the large and 28 on the smaller.</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of students on the large bus = 42

Number of students on the small bus = 40% of the students

2. How many total students are on the two buses?

For answering the question, we will use the Rule of Three Simple, this way:

42 students are 60% of total students, how much students are the 100%?

Total students = 42 * 100/60

Total students = 4,200/60 = 70

<u>There are 70 students on the two buses, 42 on the large and 28 on the smaller.</u>
