1) Write these using index notation: a. 2 X 2 X 2 X 2 b. 5 X 5 X 5 X 7 X 7
1 answer:
Answer:
a)
b) x
Step-by-step explanation:
You can group together like base values, so 3 x 3 x 3 x 3 x 3 becomes 3 to the power of 5. All it means is that you are multiplying the base value (in this case 3) by itself 5 times.
Index notation makes it easier in more complex equations to solve, as its simpler and doesn't take up as much space.

Answer:
Step 5
Step-by-step explanation:
The mistake is in step 5.
The previous step was
The order operations, PEDMAS, must be applied:
We have Addition and Division here,
Using PEDMAS, we must divide first to get:
We can now add to get:
Therefore the mistake occurred at step 5
Answer:
Step-by-step explanation:
The square root property requires a quantity squared by itself on one side of the equation. The only quantity squared is x, so divide both sides by 2 before applying the square root property.
The x variable should be isolated on one side of the equation. The x variable is squared so before performing the square root property where we take the square root of both sides, we divide both sides by 2, then take the square root of both sides.
Dividing both sides by 2.
Taking the square root of both sides.
