Which on the following is equivalent to (a 1/2 * b 1/2) ^1/2 ?

a^(1/4)  * b^(1/4)

Step-by-step explanation:

(a^ 1/2 * b^ 1/2) ^1/2

We know that we can separate the terms

a^1/2 ^1/2  * b^1/2 ^1/2

We also know that a^b^c = a^(b*c)

a^(1/2 *1/2)  * b^(1/2 *1/2)

a^(1/4)  * b^(1/4)

because 1.2 isnt half of 6 duh

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.
