Step-by-step explanation:

(3×10^2 )×(2×10^−4 )=
In the parenthesis, since exponents come before multiplication in the order of operations, we need to do the exponents first.
(3 • 100) • (2 • 1/10^4)
Now, we can just multiply everything from left to right to get:
6*10^-2
Or
.06
3x + 6 = 27
step 1. subtract 6 from both sides
3x = 21
step 2. divide both sides by three to get x alone
x = 7
