Answer 1

by substituting 1 in x

1+1+5-3+7

=11

pls mark as brainliest answer my friend

Answer 2

Answer:

11

Explanation:

Given that,x=1

So we will put 1 at every place of x in P (x)

P (1)=

${1}^{4} + {1}^{3} + 5 \times {1}^{2} - 3 \times 1 + 7$

So it will become

$1 + 1 + 5 - 3 + 7$

And we will get the answer

$11$
