Question 1:
(1/2)2 - (1/4)-2
(1/4)-2 can also be written with a positive exponent as:
42
SO:
(1/2)2 - (4)2
Squaring both numbers we get:
1/4 - 16
To simplify it, lets make a common denominator. Hence:
(1-64) / 4
63 / 4
15 3/4 Or 15.75
Question 2:
(-3xy4)-(-4x3y)6
Solving:
(-3xy4)-(-4x3y*6)
(-3xy4)-(-4x18y)
Expanding:
-3xy4+4x18y
This is the simplest form of the equation
Question 3:
[5ab2 / c3]2
Squaring the equation:
25a2b4 /c6
This can also be written as:
25a2b4 c-6
