Hello there.

How do I work out 4 + 2 x 2²?

Answer: Use PEMDAS.
2² = 4
Now you have this:
4 + 2 x 4
Multiplication is before addition.
2 x 4 = 8
Now you have this left:
4 + 8 = 12
Your answer is 12.

Hope This Helps You!
Good Luck Studying ^-^

Let's solve your equation step-by-step.2(h−8)−h=h−16Step 1: Simplify both sides of the equation.2(h−8)−h=h−16Simplify: (Show steps)h−16=h−16Step 2: Subtract h from both sides.h−16−h=h−16−h−16=−16
Step 3: Add 16 to both sides.−16+16=−16+160=0Answer:All real numbers are solutions.
