Question

Use the order of operations to simplify the expression.

Answer 1

Answer:

$50$

Step-by-step explanation:

Remember PEMDAS. First, do what's in the parentheses (P) going left to right (there's only one in this case so we dont need to). $(2 \times 5) {}^{2} - 2 \times 5 {}^{2} →(10) {}^{2} - 2 \times 5 {}^{2}$

Then do the exponents (E) going left to right. $(10) {}^{2} - 2 \times 5 {}^{2}→100 - 2 \times 25$

Now do multiplication and division (MD) going left to right (there's only one situation of multiplication in this case so we don't need to do division or go from left to right).

$100( - 2 \times 25)→100 - 50$

Now do addition (AS) going left to right (there's only one situation of subtraction in this case so we don't need to do addition or go from left to right).

$100 - 50 = 50$

The answer simplified is $50$.
