Answer:

12 and 13

Step-by-step explanation:

For the first one (a = 5 and b = -7) we plug in those values into a - b which gives us 5 - (-7) = 5 + 7 = 12. We do the same for the second one which gives us -3 - (-16) = -3 + 16 = 13.

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.

A principal of $835 in an account at 3% per quarter simple interest

Tems11 [23]

Take $835 and multiply by 0.3 and you get $25.05
If you add $25.05 to $835 you will get $860.05
Keep adding $25.05 and you will have sums of $885.10, $910.15, $935.20
So your answer is D.
