Which expression is equivalent to sqrt 80

The expression 4sqrt(5) is equivalent

Step-by-step explanation:

We can simplify the root by expresing the number in the sqrt in terms of numbers that have an integer sqrt root (such as 4, 9 etc) and following the rule :

sqrt(a*b) = sqrt (a)*sqrt(b)

To do that we do the prime factorization of 80 as follows:

80/2

40/2

20/2

10/2

5/2

Prime factorization : 2*2*2*2*5 = 4*4 *5

So we have:

sqrt(80)=sqrt(2*2*2*2*5)= sqrt(4*4*5)=sqrt(4)*sqrt(4)*sqrt(5)=2*2*sqrt(5)=4sqrt(5)

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
