Evaluate the expression (5x^2)^3/(10y)^4 for x=10 and y=5
a.15/128
b.60
c.5/256
d.20
can someone show me how to do this

The answer is option D i.e. 20

Step-by-step explanation:

We have the expression

((5x^2) ^3)/(10y)^4

and values of x=10, y=5

Putting the values of x and y in the expression

((5×10^2)^3)/ (10×5)^4

= (5×100)^3/(50^4)

= (500^3)/6250000

125000000/6250000

= 20

So the expression (5x^2)^3/(10y)^4  is evaluated to 20

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.
