Simplify the expression and enter your answer below. (17 ^1/7)^7
Answer: 17
Step-by-step explanation:
The simplification of the expression [tex]{{17 }^{1/7}}^{7}[/tex]would be 17.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping are mathematical symbol; which can also be used to indicate the logical syntax's order of operations and other features.
Based on the law of exponents power of a power property we have:
[tex](a^b)^c = a^{b \times c}[/tex]
Therefore:
[tex]{{17 }^{1/7}}^{7}[/tex]
[tex]{{17 }^{1/7}\times^{7}[/tex]
17

The formula for the pH of a solution of hydronium ions is given by the logarithmic equation pH=-log [H3O+], where [H3O+] is the hydronium ion concentration. Find the pH of a certain agricultural product with the hydronium ion concentration of 3.2 x 10-4
Answer:
3.5
Step-by-step explanation:
The formula for the pH of a solution of hydronium ions is given by the logarithmic equation pH=-log [H3O+], where [H3O+] is the hydronium ion concentration. Find the pH of a certain agricultural product with the hydronium ion concentration of 3.2 x 10^-4
We have the Logarithmic equation
pH=-log [H3O+],
We have the hydronium ion concentration = 3.2 x 10^-4
Hence,
pH = - log[3.2 × 10 ^-4]
pH = 3.4948500217
Approximately
pH = 3.5
Therefore, the pH of a certain agricultural product with the hydronium ion concentration of 3.2 x 10^-4 is 3.5
What is the point-slope equation of the line that is perpendicular to the line shown and passes through (-4, -3)?
Answer:
y+3= -4x
Step-by-step explanation:
general equation is (y-y1) = m(x-x1)
m=rise/run= -4/1 (is negative because looking from left to right on the graph it goes downward)
pick any point on the line to put in. the equation for example (0,-3)
y+3= -4x

how do you find the percentage of exponential decay?
Answer:
When an original amount is reduced by a consistent rate over a period of time, exponential decay is occurring. This example shows how to work a consistent rate problem or calculate the decay factor. The key to understanding the decay factor is learning about percent change.

Kayla squared a number x and added this result to -6.5. This gave her an answer of 42.5.
What is the equation and one of the solutions to this equation?
A.X2 + (-6.5) = 42.5; 2 = 7
B.X2? + (-6.5) = 42.5; 2 = 6
C.2x+ (-6.5) = 42.5; x = 24.5
D.2x+ (-6.5) = 42.5; I = 18
Answer:
7, -7
Step-by-step explanation:
x^2-6.5= 42.5 add 6.5 to both sides
x^2= 49
The square root of 49 is 7 and -7.

Mario claims that if the dinominator of a fraction is a prime number, then its decimal form is a repeting decimal. Do you agree? Use an example to explain
Answer:
I do not agree because Mario's claim is not general.
Step-by-step explanation:
Prime numbers: These are a set of numbers that are divisible by 1 and itself only. Examples are: 2, 3, 5, 7. 11 etc.
And a denominator is the divisor in a given fraction.
Considering the following fractions whose denominators are prime numbers:
[tex]\frac{2}{3}[/tex] = 0.66666666...
[tex]\frac{1}{7}[/tex] = 0.142857142
[tex]\frac{5}{11}[/tex] = 0.45454545...
[tex]\frac{3}{13}[/tex] = 0.23076923
[tex]\frac{1}{7}[/tex] = 0.142857142
It could be observed that Mario's claim is not a general principle which is applicable to all fractions with a prime denominator. Thus, I do not agree with his claim.
