Answer:
c = 7
d = 5
Step-by-step explanation:
Notice that in the first expression, x^c is inside a square root, and only perfect squares can be extracted from it. On the simplified form shown on the right hand side, we have x^3 outside the root and a single "x" left inside. In order for such to happen (x^3 get outside the root) there must have been an x^6 inside the square root. This together with the sole "x" that was left in the root, totals seven factors of x that should have been originally inside the square root:
x^6 * x = x^7 therefore c was a "7"
In the second expression we have a CUBIC root, so only perfect cubes can get extracted from it. Since there is one factor "x" shown in the simplified form (right hand side of the equal sign), that means that it must have been an x^3 (perfect cube) apart from the x^2 that was left inside the root. This makes the original power of x to be a 3 + 2 = 5.
Therefore d = 5
You do 420/4 so therefore it would be 105 miles per square feet of the square.
They are not congruent because they are the same shape just flipped around
Remark
To find any common denominator, write down all the prime factors and pick out what you need to make an LCD.
Method
x has one x
2x^2 = 2 * x * x
Your LCM is
one 2
two xs.
LCM = 2*x*x
LCM = 2x^2
