3 is being squared that is an exponet
so the times its self 2 times
3*3=9
so the problem would become:
5+9-7+1
The Inequality shown here is :
Multiply the denominators to be the same Lowest common multiple. when the denominators are both the same you can add the numerators together
e.g. 3/5 + 2/10
= 6/10 + 2/10
= 8/10
I'm not all that sure but hopefully this is right...
x=20+0.08x
Answer:

4² =16
5² =25
Step-by-step explanation:
Take the perfect squares and determine if 17 is closer to the 2 square roots it is in-between. In this case, 17 is closest to 16.
