Evaluate the expression. a3b2c-1d

Evaluate a2b2c1d

If a = 2, b = 4, C = 10, d = 15

Express your answer

as a reduced fraction.

Please help

Answer:

3/4 if meant

is

Step-by-step explanation:

So the expression we want to evaluate for

is

Please make sure I typed the expression and the values for the letters right.

Plug in the given values:

In the following step I said 2^3 equals 8 because 2^3 means 2*2*2. I also got rid of the negative exponents by taking reciprocal.

In the following step I said 4^2=16 because 4^2 means 4*4. I also wrote 10^1 as 10.

In the following step, I'm going to rewrite everything as a fraction if it isn't already a fraction. 8=8/1 and 15=15/1.

To multiply fractions, you just multiply straight across on top and straight across on bottom.

Actually performing the multiplication:

Time to reduce:

I divided top and bottom by 10 to get this.

One more time for reducing:

I divided top and bottom by 4 to get this.

Step-by-step explanation:

for a³b²c-1d

given

a=2

b=4

c=10

d=15

a³b²c-¹d

=(2³4²10^-1*15

=2³4²15/10

=8*16*15/10

=8*8*3

=64*3

=192

now

a³b²c¹d

=(2³4²10 15)

=(8*16*10*15)

=120*16*10

=1200*16

=19200

COLLEGE

Officer Brimberry wrote 8 tickets for traffic violations last week, but only 7 tickets this week. What is the percent decrease? Give your answer to the nearest tenth of a percent.

About 12%. you have to subtract 8 by 7 which = 1. Then you would divide one by 8 which is the original number. This would give you .125 which is better to just put as 12%.

The answer is ten percent.

MIDDLE SCHOOL

In the class there are 29 students. 17 like science, 15 like French, 8 like both. Others like math. How many like math?

my solution

n(U)=29

n(S)=17

n(F)=15

n(f intersection s)=8

now

no of maths like

29=17+15+x+8

x=5

hence 5 student likes maths
