0.7n + 0.8n = 2.1
1.5n = 2.1 (add like terms(0.7+0.8=1.5))
n=2.1/1.5 (get en on its own)
n=1.40

4-3=1 denominator never changes may i be marked brainliest?
Answer:
1)Take the smallest power common
2) simply the bracket
3) multiply with the power taken common
Example:
5×10⁶ - 4×10³
Smaller power is 3, so take 10³ common:
10³[(5×10²) - 4]
10³[500 - 4]
10³(496)
496×10³
4.96×10⁵
