PLEASE HELP ME DO THE ODDS PLEASE
i’ll give brainiest

then answer is digits ending with 1,3,5,7,...

Step-by-step explanation:

5. √7×√14. split √14 into √7 and √2. √7×√7×√2 = 7√2

7. 4√3×3√18. split √18 into √3 and √6. 4×3×√3×√3×√6 = 36√6

9. √50p^5. split into √25×√2×√p^4×√p = 5p²√2p

11. √56m²n^4p^5. split into √4×√m²×√n^4×√p^4×√14×√p= 2mn²p²√14p

13. √2/10. simplify to √1/5. Rationalize by multiplying top and bottom by √5. you get √5 over √5×√5. √5×√5 = 5 so you get √5/5

15. √3/4 × √4/5. Reduce the numbers by multiplying 3/4 and 4/5. You get √3/5. Then you rationalize like you did in question 13. Multiply top and bottom with √5. you will get √15/5

17. √3k/√8. split √8 into 2√2. Then multiply top and bottom by √2. You will get √3k√2/2×2. That simplifies into √6k/4

19. √4y/3y². Simplify the expression by dividing out the y. You get √4/3y. Now take the root of the numerator and denominator separately. 2/√3y. Now rationalize. multiply top and bottom with √3y. You will get 2√3y/3y

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21
