Verified answer

Question A

(7x^7) (32) x³

----------------------

4x² 56 x

x^7

Question B

Presentation is not good I`m afraid.

I think you mean , NOT as given , but :-

(y - 6)² / 5

---------------

(5y - 30) / 25

25 (y - 6)²

---------------

25 (y - 6)

y - 6

PS

Brackets MUST be used in questions !

7x^7/ 4x^2=7x^5/4

so a=(7x^5* 32x^3)/(4* 56x)

=224* x^8/224x

=x^7

(5y-30)/25=5(y-6)/25=(y-6)/5

so b=(y-6)^2/5 * 5/(y-6)

=(y-6)^(2/5 -1) *5

=(y-6)^(-3/5) *5

=5 / ((y-6)^(3/5))

when you divide a fraction, it's equivalent to multiply by the reciprocal.

so for both parts, flip the second fraction and then multiply the two fractions together.
