How to simplify
(2a^2 b^3 c^4)^3 (-3ab)^2 (-b^3c)^3


Sagot :

Step by Step Solution:
STEP 1:

1.1 Negative number raised to an even power is positive

For example let's look at (-7)6 , where (-7) , a negative number, is raised to 6 , an even exponent :

(-7)6 can be written as (-7)•(-7)•(-7)•(-7)•(-7)•(-7)

Now, using the rule that says minus times minus is plus, (-7)6 can be written as (49)•(49)•(49) which in turn can be written as (7)•(7)•(7)•(7)•(7)•(7) or 76 which is positive.

We proved that (-7)6 is equal to (7)6 which is a positive number

Using the same arguments as above, replacing (-7) by any negative number, and replacing the exponent 6 by any even exponent, we proved which had to be proved

Equation at the end of step 1:

(((((2•(a2))•(b3))•(c4))3)•32a2b2)• -b3c


STEP 2:

Equation at the end of step 2:

((((2a2 • b3) • (c4))3) • 32a2b2) • -b3c

STEP 3:

Multiplying exponential expressions :

3.1 b11 multiplied by b3 = b(11 + 3) = b14

Multiplying exponential expressions :

3.2 c12 multiplied by c1 = c(12 + 1) = c13

Final result :
( -23•32a8b14c13)
