Answer:
Explanation:
<u>To solve this, we must follow the PEMDAS rule:</u>
Parenthesis
Exponents
Multiply
Divide
Add
Subtract
<u>So lets start on the left equation:</u>
<u>Since parenthesis is first, we must do this:</u>
(150 - 168 + 24)
168 + 24
==> 192
192 - 150
==> 42
<u>So right now we have:</u>
( + 42 -
<u>Do the exponents now:</u>
and = 25
64 + 42 - 25
64 + 42
==> 106
106 - 25
==> 81
<u>So now we have 81 for the left equation, now for the right:</u>
(3 × 5 - 3 × 2²)
<u>Exponents first:</u>
(3 × 5 - 3 × 4)
3 * 5
==> 15
3 * 4
==> 12
15 - 12
==> 3
<u>So now we should be with:</u>
81 divided by 3
81 ÷ 3
==> 27
