What is the value of y in this simplified expression?

11^-4/11^-8=11^y

a.-12

b.2

c.4

d.32

choice C. y = 4

Step-by-step explanation:

Simplify  11^-4 / 11^-8

=  11^(-4 - (-8) ) =  11^(-4+8)  =  11^4

so

11^4 = 11^y

means  y = 4

the first one

step-by-step explanation:

just id the test.

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
