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
Answer: 9x + 3y = 12
Alternative forms: y = 0.4 OR y = 
Answer:
72 degrees.
Step-by-step explanation:
As it is a right angled triangle and if the smaller acute angle = x degrees then:
x + 4x + 90 = 180.
5x = 90
x = 18 degrees.
The larger acute angle = 4x = 4*18
= 72 degrees.
