Well if tour asking for 3 number combination from the numbers 0-9, there are 1000 combinations
Well your answer is 5^-8=0.00000256 * 5^4=0.0016, so your answer is 0.0016. Basically, what you do is 5x(-8) get your answer, then do 5x4, get your anser and then multiply both answer. And boom, you solved it!

Answer: x = log₃₇(12)
Step - by - step explanation:
1. Remove the variable from the exponent using logarithms
37^x=12
Take the common logarithm of both sides of the equation:
log₁₀(37^x)=log₁₀12)
Use the log rule: log_a(x^y)=y*log_a(x) to move the exponent outside the logarithm:
x*log₁₀(37)=log₁₀(12)
2. Isolate the x-variable
x*log₁₀(37)=log₁₀(12)
Divide both sides of the equation log₁₀(37) by:
x = log₁₀(12) / log₁₀(37)
Use the formula
to combine the logarithms into one:
x=log₃₇(12)
Decimal form:
x=0.6881648129099501

Ratio of student to teacher = 17:3
Let the total number of students and faculty = x
Then
Number of students = 17X
Number of teachers =3X
So
17X+3X=740
20X = 740
X = 37
Then the number of students = 17*37

= 629</span>
Number of teachers = 3*37

Answer:
38 cm
Step-by-step explanation:
The perimeter of a rectangle is given by
P =2(l+w)
P =2( 2x+1 + x)
Combine like terms
P = 2(3x+1)
Distribute
P = 6x+2
Let x=6
P = 6*6+2
= 36+2
= 38 centimeters
