\bf 2x+\sqrt{4x^2}+\sqrt[3]{8x^3}\qquad 
\begin{cases}
4\to 2^2\\
8\to 2^3
\end{cases}\qquad thus
\\\\\\
2x+\sqrt{2^2x^2}+\sqrt[3]{2^3x^3}\implies 2x+\sqrt{(2x)^2}+\sqrt[3]{(2x)^3}
\\\\\\
2x+2x+2x=\boxed{6x}

Use the order of operations to find the value of the following expression.
Romashka-Z-Leto [24]
10² - 2 (8) + 11 . Use PEMDAS, which is the order of operation to follow:

P = parenthesis  → 10² - 2x8 +11
E = exponent     → 100 - 2x8 +11
M = Multiplication → 100 -16 +11
D = Division         → NO DIVISION
A = Addition        → 111 -16
S = Subtraction  →  95 (answer 3)

Apply the same logic for the 2nd exercice and you will find 26 (I don't see the 26 in your answer but I am sure it's 26)

What is the solution to 6x=30
Tasya [4]

Answer:

\boxed{x=5}

Step-by-step explanation:

Division property of equality- is dividing both sides of an equation by the same non-zero number it does not change the equation.

First you had to divide by six from both sides of an equation form.

\frac{6x}{6}= \frac{30}{6}

30/6=5

30/5=6

5*6=30

6*5=30

x=5

5=x

Final answer: \boxed{x=5}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.
