Just remember the syllables PEMDAS which stand for Parentheses, Exponents, Multiplication, Division, Addition and Subtraction. If you can’t remember it, just write it on the side of your paper. But make sure to use it in that order.

Answer:

1) 5x³ + 3x²

2) 25 - 3x⁵

3) -4ab + 2a² + 26

4) p²q³ + pq

Step-by-step explanation:

Like terms are expressions like 3x and 2x or 5x² and 8x².

1) x² + 5x³ + 2x²

5x³ + 3x²

2) -2x⁴ + 16 + 2x⁴ + 9 - 3x⁵

-2x⁴ + 2x⁴ + 25 - 3x⁵

25 - 3x⁵

3) ab - a² + 4² - 5ab + 3a² + 10

ab - a² + 16 - 5ab + 3a² + 10

ab - a² - 5ab + 3a² + 26

ab - 5ab + 2a² + 26

-4ab + 2a² + 26

4) 3p²q² - 3p²q³ + 4p²q³ - 3p²q² + pq

3p²q² + p²q³ - 3p²q² + pq

p²q³ + pq

8 times 3 is 24 so now put your fraction over twenty four
15/24=5/8
15/24 so fifteen out of twenty fourths of the package is what she has. She takes ten out of the fifteenths because fifteen divided by three is five then multiply by two is ten. Then divide by five and you get two.
15/24. 10-> 15/24 cause... 15 divided by 3 ( from the two thirds she cooked) is 5 then * by 2... 5*2=10
