Answer:
Step-by-step explanation:Use the square root on both sides:
x
–
5
=
±
√
3
Add 5 to both sides:
x
=
5
±
√
3
This breaks into two equations:
x
=
5
+
√
3
and
x
=
5
−
√
3
Use the square root on both sides:
x
–
5
=
±
√
3
Add 5 to both sides:
x
=
5
±
√
3
This breaks into two equations:
x
=
5
+
√
3
and
x
=
5
−
√

Step-by-step explanation:
3^-n=0.2
1/3^n=0.2
1=0.2(3^n)
3^n=1/0.2
3^n=5
(3^n)²=5²
(3^n)²=25
