Answer:

Step-by-step explanation:

Start by combing the terms on the right. 3b - 8 = 3b - 2 because 7b - 4b is going to equal 3b

You are now officially stuck. The moment you try and put the 3b's on the same side of the equation, they will cancel out. There is no unique solution.

If the expression x^{-\frac{3}{2}}y\sqrt{36xy^2}x − 2 3 y 36xy 2 is written in the form ax^by^cax b y c , then what is the p

Mekhanik [1.2K]

Answer:

-12

Step-by-step explanation:

The given expression is

$x^{-\frac{3}{2}}y\sqrt{36xy^2}$

We have to rewrite the given function in the form of

$ax^{b}y^c$ ....(i)

then we have to find the product of a,b and c.

The given expression can be rewritten as

$x^{-\frac{3}{2}}y\sqrt{36}\sqrt{x}\sqrt{y^2}$

Using properties of exponents we get

$x^{-\frac{3}{2}}y6x^{\frac{1}{2}}y$ $[\because \sqrt[n]{a}=a^{\frac{1}{n}}]$

$6x^{-\frac{3}{2}+\frac{1}{2}}y^{1+1}$ $[\because a^ma^n=a^{m+n}]$

$6x^{-1}y^{2}$ ...(ii)

On comparing (i) and (ii), we get

$a=6,b=-1,c=2$

Product of a,b and c is

$abc=(6)(-1)(2)=-12$

Therefore, the product of a,b, and c is -12.

Carlos scored 152, 138, and 160 in 3 consecutive

bezimeni [28]

Method 1 :
(152+138+160)÷3 = 150

(152+138+160+198)÷4 = 162

Then his average score will increase

Method 2 :
Since 198 > 150 then the average will increase automatically.
