Question

Quiz 6. Simplify the expression. 4 (10 – 4)² + 4) A6 B 36 D 12

Answer 1

This is all about operations priority! We have to perform the operations in the right order, remembering that parentheses come first, then powers, then multiplications and then additions:

Start with

$4(10-4)^2+4$

Perform the operations inside parenthesis first:

$4\cdot 6^2+4$

Perform the square:

$4\cdot 36+4$

Perform the product:

$144+4$

Perform the sum:

$148$

Note: you have an extra parenthesis at the end, and none of the options meets the result. I'm afraid that there's a typo in the question, but this should still give you a valid strategy to solve the actual exercise.

Answer 2

Answer=148
You subtract the numbers
Then evaluate the power
Then you multiply the numbers
Finally you add the numbers
