Please help me simplify these expressions

Mathematics

Stella [2.4K]3 years ago

Answer:

1. x^{11}     2. 10n^{9}   3.  6x^{10}

Step-by-step explanation:

1.   x^{11}

Imagine the expression is written like this:

(x)(x) *  (x)  * (x)(x)(x) * (x)(x)(x)(x)(x)

Simply add up the number of x's and have that number be the exponent.

There are 11 x's, so it will be x^{11}

2. 10n^{9}

Do the same as above, but this time remember that two negatives equal a positive.

10n^{9}

3. 6x^{10}

Again, two negatives equal a positive.

-3 x 2 x -1 = 6

Do the same as the above two.

6x^{10}

Answer:

Step-by-step explanation:

If base of variable is same, add the powers

1) x² * x * x³ * x⁵ = x²⁺¹⁺³⁺⁵ = x¹¹

2) -2n² * -n⁴ * 5n³ = (-2* -1*  5 ) *n²⁺⁴⁺³ = 10n⁹

3)-3x⁴ * 2x⁵ * - x = (-3 * 2 * -1)* x⁵⁺⁴⁺¹ = 6x¹⁰

Solve for c.<br><br> 5c+16.5=13.5+10c
Kruka [31]

Answer:

c = 3/5

Step-by-step explanation:

5c+16.5=13.5+10c

Subtract 5c from each side

5c-5c+16.5=13.5+10c-5c

16.5 = 13.5 +5c

Subtract 13.5 from each side

16.5 -13.5 =13.5-13.5 +5c

3 = 5c

Divide by 5

3/5 = 5c/5

3/5 =c

What is this just tell me what the L AND W ='s please
andreyandreev [35.5K]
You didn't show us much of the page with the question on it,
so we can't be sure of exactly what you're working on in math.

If you're working with things like squares and rectangles, then
'L' and 'W' are often used to represent the Length and Width of
shapes drawn on paper, or even Length and Width of 3D objects
like blocks or boxes.
