saw5 [17]

Answer:

$\large\boxed{2.02\times10^{-7}}$

Step-by-step explanation:

The scientific notation:

$a\cdot10^k\\\\1\leq a$

We have:

$(8.08\times10^{-10})\div(4.0\times10^{-3})\\\\=\dfrac{8.08\times10^{-10}}{4.0\times10^{-3}}\\\\=\dfrac{8.08}{4}\times\dfrac{10^{-10}}{10^{-3}}\qquad\text{use}\ \dfrac{a^n}{a^m}=a^{n-m}\\\\=2.02\times10^{-10-(-3)}\\\\=2.02\times10^{-7}$

Simplify 23 + 6c + 8d - 7d - 6

gladu [14]

First, identify the terms.
23
+6c
+8d
-7d
-6
Now combine like terms. Like terms are terms with the same variable (i.e. 1x and 3x)
23 and -6
6c
8d and -7d
Now combine!
23 - 6 = 17
6c = 6c
8d - 7d = 1d
So the answer is 17 + 6c + 1d
