Question

Given a +b=7 and a-b=3, find: 3^a/3^b

Answer 1

Answer:

First of all you will solve the two equations simultaneously to get the values of a and b after that you use it to find, 3^a /3^b

Step1. a+b=7..... (1)

a-b=3.......(2)

Now take eqn(1) +eqn(2),

Implies 2a=10

Dividing both sides by 2,

Then a=5

Put a=5 into eqn(1),

Implies 5+b=7

b=7-5

b=2

Therefore the values of a and b are 5 and 2

Step2

Now find 3^a/3^b,

Substitute the vaues of a and b into the function.

Implies 3^5/3^2=243/9

=27

Therefore 3^a/3^b=27

Step-by-step explanation:

Above

Answer 2

Answer:

a is 5 and b is 2 so it's 3 to the power of 5 divided by 3 to the power of 2
