Answer:

Step-by-step explanation:

PEMDAS:

Parenthesis first:

8^2 + 4 (8 - 14)^2

8^2 + 4 (-6)^2

Exponents second:

8^2 + 4 (-6)^2

64 + 4 (36)

Multiply third:

64 + 4 (36)

64 + 144

Add last and solve:

64 + 144 = 208

Simplify ^3 sq try (-0.05)^24

Bogdan [553]

Answer:

$\sqrt[3]{\left(-0.05\right)^{24}}=0.05^8$

so option D is correct.

Step-by-step explanation:

Given the expression

$\sqrt[3]{\left(-0.05\right)^{24}}$

$\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a}=a^{\frac{1}{n}}$

$\sqrt[3]{\left(-0.05\right)^{24}}=\left(\left(-0.05\right)^{24}\right)^{\frac{1}{3}}$

$\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc}$

$=\left(-0.05\right)^{24\cdot \frac{1}{3}}$

$=\left(-0.05\right)^8$

$\mathrm{Apply\:exponent\:rule}:\quad \left(-a\right)^n=a^n,\:\mathrm{if\:}n\mathrm{\:is\:even}$

$=0.05^8$

Hence, the simplification will be:

$\sqrt[3]{\left(-0.05\right)^{24}}=0.05^8$

Therefore, option D is correct.

Working together, 5 friends collected 15 5/8 bags of food for the homeless. On average, how many bags of food did each friend co

Effectus [21]

15 5/8 divided by 5

First, we turn the 15 5/8 to a mixed number: 8 * 15 + 5 = 125/8

125/8 divided by 5/1 (which is equal to 5)

Next, we do Keep Change Flip.

Keep 125/8 the same, change the division to multiplication, and turn the 5/1 to 1/5.

1 * 125 = 125

8 * 5 = 40

Then, we get 125/40 = 3 5/40 BUT WAIT

We can reduce it once more! Divide 40 by 5

Each friend collected 3 1/8 bags of food.

Cost of book (x) exceeds twice the cost of pen (y) by Rs 10. This

Eddi Din [679]

The relationship between the cost of books and pens is an illustration of linear equation.

The linear equation is (a) $x - 2y - 10 =0$

From the question, we have:

x exceeds 2 times y by 10

Rewrite as:

x exceeds 2y by 10

Exceed means plus (+)

So, we have:

$x = 2y + 10$

Equate the above equation to 0

$x - 2y - 10 =0$

Hence, the required equation is (a) $x - 2y - 10 =0$
