P(-5) = (-5)³ - 6(-5)² - 7(-5) + 60

p(-5) = -125 - 6(25) - (-35) + 60

p(-5) = -125 - 150 + 35 + 60

p(-5) = -275 + 95

p (-5) = -180

so is x + 5 a factor of polynomial ( NO) because when make a substitution by -5 the answer will not be 0

Answer:

Solving the expression $\frac{\sqrt[3]{7} }{\sqrt[5]{7} }$ we get $\mathbf{7^{\frac{2}{15}}}$

Option D is correct option.

Step-by-step explanation:

We need to solve the expression: $\frac{\sqrt[3]{7} }{\sqrt[5]{7} }$

We know that

$\sqrt[3]{x}=x^{\frac{1}{3}$ and $\sqrt[5]{x}=x^{\frac{1}{5}$

Using above rule:

$\frac{\sqrt[3]{7} }{\sqrt[5]{7} }\\=\frac{7^{\frac{1}{3}}}{7^{\frac{1}{5}}}$

Now, we know the exponent rule if bases are same and divided then exponents are subtracted i.e: $\frac{a^m}{a^n}=a^{m-n}$

Using the exponent rule

$=7^{\frac{1}{3}-\frac{1}{5} }\\Simplifying\:exponents\\=7^{\frac{5-3}{15}}\\=7^{\frac{1*5-1*3}{15}}\\=7^{\frac{2}{15}}$

So, solving the expression $\frac{\sqrt[3]{7} }{\sqrt[5]{7} }$ we get $\mathbf{7^{\frac{2}{15}}}$

Option D is correct option.

The number 1953125 is equal to 5^9. Explain how the information above tells you that it is not a square number. I've tried the a

Answer:

$5^{9}$ can not be expressed as a square of any other number.

Step-by-step explanation:

The number 1953125 is equal to $5^{9}$ .

Now, the above statement gives an idea that 1953125 i.e. $5^{9}$ is not a square number as 9 is not a multiple of 2.

So, we can not express $5^{9}$ as a square of any other number.

We can only express $5^{9}$ as $(5^{4} )^{2} \times 5$ .
