Can someone please help me ASAP do number 3

your answer is 5^9

Step-by-step explanation:

first you would multiply the terms with the same base by adding their exponents it should look like this:5^3 + 6

then you add the numbers and you should get 5^9

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

it would open into a square depending on the type of envelope i’m not sure about the second part
