4 3/2 solve in indices​
mylen [45]

Answer:

(2^2)^3/2 = (2)^3 = 8

Step-by-step explanation:

So to solve (4)^3/2 ,you have to realise that you need to remove the denominator in the exponent value which in this case is 2

In order to remove the 2,you would need a 2 in the numerator of the exponent .While understanding all this the value 4 can be equated as 2^2.

Thus your means of getting a 2 in the numerator is solved by simply replacing the 4 with 2^2

Thus what you will get is (2^2)^3/2

Now we have a property in exponent where

(x^m)^n = (x)^mn

Thus (2^2)^3/2 = (2)^3 =8

The weight of a box of chocolates is 2.2 pounds. After taking out 75% of the chocolates, the remaining chocolates and the box we
Margarita [4]

Answer: The weight of the box is 0.2 pounds and the weight of the chocolates before any chocolates were taken out is 2 pounds

Step-by-step explanation:

Let x represent the weight of the box only.

The weight of the box of chocolates is 2.2 pounds. It means that the weight of the chocolate only is

(2.2 - x) pounds

After taking out 75% of the chocolates, the remaining chocolates and the box weigh 0.7 pounds. It means that

2.2 - 0.75(2.2 - x) = 0.7

2.2 - 1.65 + 0.75x = 0.7

0.75x = 0.7 + 1.65 - 2.2

0.75x = 0.15

x = 0.15/0.75

x = 0.2 pounds

The weight of the chocolates before any chocolates were taken out is

2.2 - x = 2.2 - 0.2 = 2 pounds
