1. $\frac{7^8}{7^6}=49$

2. 7

3. 18

Step-by-step explanation:

Question 1:

Given:

The expression to simplify is $\frac{7^8}{7^6}$ .

We use the property of exponent $\frac{a^m}{a^n}=a^{m-n}$

Therefore, $\frac{7^8}{7^6}=7^{8-6}=7^2=7\times 7 = 49$

Question 2:

Given:

The expression to simplify is $7(\frac{1}{2}+\frac{1}{2})$ .

We add the fractions first inside the parenthesis.

So, $\frac{1}{2}+\frac{1}{2}=\frac{1+1}{2}=\frac{2}{2}=1$

Now, 7(1)=7

Question 3:

The first five prime numbers are 1, 2, 3, 5, and 7.

Therefore, the sum of these five numbers is given as:

1+2+3+5+7=18

The solution is x = 0.83

Step-by-step explanation:

We are given the following equation:

$e^{3x} = 12$

To isolate x, we apply ln, which is the inverse of the exponential. So

$\ln{e^{3x}} = \ln{12}$

$3x = \ln{12}$

$x = \frac{\ln{12}}{3}$

Using a calculator:

x = 0.83

The solution is x = 0.83
