A license plate is to consist of 4 digits followed by 2 uppercase letters. determine the number of different license plates poss
Rudik [331]
To determine all the different possibilities, you will find the possible choices for each position in the license and multiply them together.
1st digit - 1/5 (1,3,5,7,9)
2nd digit-1/4(4 left from above)
3rd digit-1/8 (10-2=8 possible)
4th digit-1/7 (8-1)
5th digit-1/26 (26 letters)
6th digit-1/25 (26-1)

1/5 x 1/4 x 1/8 x 1/7 x 1/26 x 1/25 =1/728000 which means there are 728000 possibilities.

Factorize the following expression ab-a-b+1
dolphi86 [110]

Group 'em together

a b − a + 1 − b

a b − a = a ( b − 1 )

Notice that there will be a 1 as without it it'll simply be  ab

1 − b = 1 ( 1 − b )

Notice that it doesn't match with the upper one... so we'll change the signs

1 ( 1 − b ) = − 1 ( b− 1 )

(try to multiply them now!!

Jot them down in one expression

a ( b − 1 ) − 1 ( b − 1 )

You get!!!!!!

( a − 1 ) ( b − 1 )

Answer:

x^6

Given (x^8)^3/4

To find : simplified as much as possible, x is raised to what exponent.

Solution : We have given that   (x^8)^3/4

By the exponential rule : x^a(b) = x^ab

Then we have

=x^(8/4 *3)

=x^(2 *3)

=x^6
