Answer:
9
Step-by-step explanation:
Input 3 for x
f(x)=2^3+1
f(3)=2^3+1
f(3)=8+1
f(3)=9
9√2 is squared first.
so its 162.
now according to Pythagoras theorem,
x2+x2=162
2x^2= 162
x^2= 162÷2
x^2= 81
x= √81
x=9
The algebraic expression for a phrase is: 
.
Hope this help.
Simplified :(5x+4y)(5x−4y)
=(5x+4y)(5x+−4y)
=(5x)(5x)+(5x)(−4y)+(4y)(5x)+(4y)(−4y)
=25x2−20xy+20xy−16y2
=25x2−16y2
hope this helps!
