Question

The square of r increased by a quantity that is fifty times the cube of k

Answer 1

That would be
                          √r + 50k^3

Answer 2

Answer: Our required expression would be $r^2+50k^3$

Step-by-step explanation:

Since we have given that

The square of r increased by a quantity that is fifty times the cube of k

Square of r means

$r^2$

cube of k means

$k^3$

50 times the cube of k means

$50k^3$

increased by is expressed by addition operator.

So, our equation becomes,

$r^2+50k^3$

Hence, our required expression would be $r^2+50k^3$
