Question

If k=2, what is the value of k3−(k−10)+4k?

f 24 g 22 h 8 j 6

Answer 1

2 x 3 - (2-10) + (2 x 4) =
6 - (-8) + 8
6 + 8 + 8 = 22
So the answer would be g, 22.

Answer 2

The given expression is
`k^3-(10-k)+4k`.

Substitute the numerical value of k=2 in the above expression,

`2^3-(2-10)+4*2=8+8+8=24`.

The value of the given expression is
`24`.

The correct option is (f).
