Answer:
1) 8zs² × 4z³s^5
= 32z⁴s^7
2) 5w^5 × 4w⁴
= 20w^9
3) 3r × 5r^5
= 15r^6
4) cz × 9c^5z²
= 9c^6z³
5) (1/r)⁴ × (1/r)^7 × (1/r)^6
= r^-4 × r ^ -7 × r^ -6
= r^ -17
6) 4h^6 × 2h³c²
= 8h^9c²
Hope this helps.
1. = 32z4s7 2.= 20w9 3.= 15r6 8.= 9c6z3 (i don't know 9 sorry) 10.= 8h9c2
Step-by-step explanation:
the numbers that come AFTER the letters are the powers.
x=(2y-4)/-2
x=-y+2
2(-y+2)-y=-5
-2y+4-y=-5
-3y+4=-5
-3y=-9
y=3
x=-3+2
x=-1
e
16
3 times 6 is 18 and 12 divided by 6 is 2
18 - 2 =16
