Simplify the expression show all of your work 3+5 squared -9÷3×4= Please help

dexar [7]

Answer:

Step-by-step explanation:

(5√3*√3)+(5√3*5)+(-1*√3)+(-1*5)

5*3+25√3-√3-5

15+24√3-5

**24√3+10**

Then to solve the second, apply division rules within the radical. This means you can cancel an m^1 and n^4 from the bottom and top of the fraction. This leaves...

3√(88m^19*n^8)

(That might be all you need to do, otherwise you can take the square root of each number in the term giving...

3(√88)*m^9.5*n^4)

Hope I made it clear enough

Answer:

The correct answer is A.

Step-by-step explanation:

You do not need to perform any operations to derive the correct answer from the choices provided. As you can see from the choices, the 3/4th power of 81 will turn out to be 27 ( $\sqrt[4]{81 * 81 * 81}$ ). The 3/4th power of d to the power of 24 is d to the power of 18 ( $24 * 0.75$ ).

With that being said, the most important thing to take note of is the negative symbol of the power. A negative power turns a value into its reciprocal. In this case, both the 81 and the d to the power of 24 will both go into the denominator (since the two are encompassed in a set of parentheses together) — you apply what was previously mentioned regarding what the power of 3/4 will do to 81 times d to the power of 24 — and your answer is choice A!
