Which expression is equivalent to (x^6×x^10/×^-3)^2 and why?

mixer [17]

Answer:

The solution for the given expression is $x^{38}$ , i.e option C

Step-by-step explanation:

Given expression as :

$(\dfrac{x^{6}\times x^{10}}{x^{-3}})^{2}$

Now, From the common radix method

∵ In multiplication of radix , if the radix is same , then power is added

I.e $x^{6}\times x^{10$ = $x^{6+10}$

Or , $x^{6}\times x^{10$ = $x^{16}$

Now, The expression can be written as

$(\frac{x^{16}}{x^{-3}})^{2}$

And In Division of radix , if the radix is same , then power is subtracted

So, $\frac{x^{16}}{x^{-3}}$

Or, $x^{16 - (-)3}$

Or, $x^{16 + 3}$

or, $x^{19}$

∴ The expression is now

$(x^{19})$ ²

Now, again this is written as

$x^{19}$ × $x^{19}$

I.e here again the radix is same and in multiple for, so, power is added

∴ $x^{19}$ × $x^{19}$ = $x^{19+19}$

I.e $x^{19}$ × $x^{19}$ = $x^{38}$

Hence The solution for the given expression is $x^{38}$ , i.e option C . Answer

Place the indicated product in the proper location on the grid. -2x^2y^3 · 14x^2y^3

mojhsa [17]

We have the following product:
-2x ^ 2y ^ 3 · 14x ^ 2y ^ 3
For power properties we have:
"same base add the exponents"
We have then:
(-2 * 14) (x ^ (2 + 2)) (y ^ (3 + 3))
-28x ^ 4y ^ 6
Answer:
The product -2x ^ 2y ^ 3 · 14x ^ 2y ^ 3 is:
-28x ^ 4y ^ 6

CARLOS HAS $10 MORE THAN JEREMY. JEREMY HAS $5 MORE THAN MICHELE . ALTOGETHER THEY HAVE $80 . WHAT PART OF 100 DOES MICHELE HAVE

KonstantinChe [14]

In total they have $80 so that means Carlos have 35 Jeremy have 25 and Michele have 20 then 20 divide 80 gives u the percentage out of 100 the answer is 25
