Answer:

1.3905 × 10^4

Step-by-step explanation:

First you should multiply all the two numbers  inside the parentheses

5.7 × 105=598.5

4.6 × 106=487.6

2.9 × 105=304.5

Now add the three numbers

598.5+487.5+304.5= 1390.5

scientific notation: Put the decimal after the first digit. To find the exponent count the number of places from the decimal to the end of the number.

the answer in scientific notation: 1.3905 × 10^4

I dont mind giving out 40 points to who ever answers this correctly
jenyasd209 [6]

Answer:

27/ (4  x^6 y^8)

Step-by-step explanation:

4(3x^2y^4)^3/(2x^3y^5)^4

expand

4 (3^3  x^2^4 y^4^3) / (2^4 x^3^4 y^5^4)

power of the power rule , exponents to the power are multiplied

4 (3^3  x^(2*4) y^(4*3) / (2^4 x^(3*4) y^(5*4))

4 (27  x^(8) y^(12) / (16 x^(12) y^(20))

put like terms over each other

4 * (27/16) * x^8/x*16  * y^12/y^20

when dividing exponents , we subtract the powers

27 * 4/16 * x^ (8-14) * y^ (12-20)

27* 1/4 * x^(-6) *  y^ (-8)

27/4  *  x^(-6)(y)^ (-8)

negative terms go to the denominator

27/ (4  x^6 y^8)

Solve for a.
Tanya [424]

Final Answer: All Real Numbers

Steps/Reasons/Explanation:

Question: Solve for a. 4(a + 3)=12 + 4a.

<u>Step 1</u>: Expand.

4a + 12 = 12 + 4a

<u>Step 2</u>: Cancel 4a on both sides.

12 = 12

<u>Step 3</u>: Since both sides equal, we would have infinitely many solutions.

~I hope I helped you :)~
