Multiply: (-5qr) × (-2pqr) × pq​

Mathematics
1 answer:
ahrayia [7]3 years ago
4 0

Answer:

The product of (-5·q·r) × (-2·p·q·r) × p·q is 10·q³·r²·p²

Step-by-step explanation:

The question relates to the rules of multiplication of variables and indices rules, and simplifification of an expression ;

The given expression is (-5·q·r) × (-2·p·q·r) × p·q

Therefore, we have;

(-5·q·r) × (-2·p·q·r) × p·q = (-5) × (-2) × q×q×q × r×r ×p×p = 10 × q³ × r² × p²

10 × q³ × r² × p² = 10·q³·r²·p²

∴ (-5·q·r) × (-2·p·q·r) × p·q = 10 × q³ × r² × p² = 10·q³·r²·p²

(-5·q·r) × (-2·p·q·r) × p·q = 10·q³·r²·p².

Help me with this pleaseee
Galina-37 [17]

Answer:

option c

Step-by-step explanation:

<u>Volume = Length * Width * Height </u>

this is a pretty easy problem cuz all u need to do is find which one of the options has a product of 729.

option a) 7 * 8 * 12

well 7 * 8 * 12 equals 672, so that cannot be the box

option b) 8*9*11

8*9*11 = 792. cant be the box cuz 792 does not equal 729

option c) 9*9*9

9*9*9=729

option c is the box cuz 729 = 729

Insert 5 G.Ms between 3 and 192​
never [62]

Answer:

6, 12, 24, 48 and 96.

Step-by-step explanation:

We look for a geometric sequence with first term = 3:

nth term= a1 r^(n-1)

3 r^(n-1) = 192

r^(n-1) = 192 / 3 = 64

2 ^ 6 = 64   so r = 2.

Series is 3 ,6, 12, 24, 48, 96, 192.

So 5 geometric means would be 6, 12, 24, 48 and 96.
