A textbook store sold a combined total of 332 history and chemistry textbooks in a week. The number of chemistry textbooks sold
xz_007 [3.2K]

Answer:

208 history books

124 chemistry books

Step-by-step explanation:

Let a = total number of books

b = number of history books

c = number of chemistry books

a = b + c

We know that a is equal to 332 and c = b - 84

Let's substitute this value to our equation and solve for b first. Now we get:

332 = b + ( b - 84)

332 = 2b - 84

332 + 84 = 2b

416 = 2b

b = 208

Now we can solve for c

332 = 208 + c

332 - 208 = c

c = 124

Now let's check

a = 332

b = 208

c = b - 84 = 208 - 84 = 124

√48a^4 b^5 c^3 d simplify and keep it in radical form
Morgarella [4.7K]
I will assume the square root extends all the way across.

\sqrt{48a^4b^5c^3}

\sqrt{2^4\cdot3\cdot a^4b^5c^3}

\sqrt{(2^2)^2\cdot3\cdot(a^2)^2\cdot(b^2)^2\cdot b\cdot c^2\cdot c}

\sqrt{(4)^2\cdot3\cdot(a^2)^2\cdot(b^2)^2\cdot b\cdot c^2\cdot c}

\sqrt{(4\cdot a^2 \cdot b^2 \cdot c)^2\cdot3\cdot b\cdot c}

4\cdot a^2\cdot b^2\cdot c\sqrt{3\cdot b\cdot c}

\boxed{4a^2b^2c\sqrt{3bc}}
