Answer 2

Answer:

The value of  $5x^{27} -3x^{32} +2x^{-14}$  is 4

option(c) is correct.

Step-by-step explanation:

Given that $5x^{27} -3x^{32} +2x^{-14}$

We find the value of  $5x^{27} -3x^{32} +2x^{-14}$   at x=1

That means we replace x by x= 1. then

$5x^{27} -3x^{32} +2x^{-14}$

= $5(1)^{27} -3(1)^{32} +2(1)^{-14}$

one to the power of any number it becomes one.

= 5 - 3 + 2

=7 - 3

= 4

Therefore, the value of  $5x^{27} -3x^{32} +2x^{-14}$  is 4

Hence option(c) is correct. that is '4'
