Answer:
64
Step-by-step explanation:
6.4 * 10^1
is the same as:
6.4 * 10
= 64
-5 3/4, -5, 5/12,1 1/5
$129
We can use this equation:
x - 0.45x = 70.95
0.55x = 70.95
x = $129
8^3.
= [ (6^3)^6*1/2] / [9^9]^1/2
= 6^9 / 9^9/2
= 6^9 / (3^2)^9/2
= 6^9 /3^9
= 512
= 8^3.
x = 8
Hope this helps have a great day
