Answer:

\sqrt{2^5}

Step-by-step explanation:

First, deal with the product of the two powers of 2 inside the parentheses.

The two factors are powers of 2, so add the exponents.

(2^{\frac{1}{2}} \cdot 2^{\frac{3}{4}})^2 =

= (2^{\frac{1}{2} + \frac{3}{4}})^2

You need a common denominator, 4, to add the fractions.

= (2^{\frac{2}{4} + \frac{3}{4}})^2

= (2^{\frac{5}{4}})^2

Now you have an exponent raised to an exponent. Multiply the exponents and reduce the fraction.

= 2^{\frac{5}{4} \times 2}

= 2^{\frac{10}{4}}

= 2^{\frac{5}{2}}

When a fraction is an exponent, the numerator is an exponent and the denominator is the index of the root. A denominator of 2 means a root index of 2 which means square root.

= \sqrt{2^5}

A Shopkeeper
Sergio [31]

Answer:

The cost of bicycle is Rs1000

Step-by-step explanation:

Let x be the cost of bicycle

Total profit gained by the shopkeeper by selling at labelled price = 20%

Suppose he sell the bicycles at at 5% discount

Which means that the total profit he learn after discount will be:

20% -5% = 15%

The shopkeeper earns a profit of 15% if he sells at discount.

Profit gained by shopkeeper is:

15% of x = 15/100 · x

15% of x = 0.15x

Thus the profit gained will be 0.15x. As profit gained is equal to 150, we can say that

0.15x = 150

x = 1000

The cost of bicycle is Rs1000

Need help solving algebraically!
alekssr [168]
We need to account for both x values on either side of the length, and width.
Thus, the length becomes 10 + x + x = 10 + 2x
and the width becomes 5 + x + x = 5 + 2x

For the second question, I'm assuming we don't account for the area that is covered by the garden.
Then we can say that the path is measured by: (5 + 2x)(10 + 2x) - 50, which is the area of the garden itself.

(5 + 2x)(10 + 2x) - 50 = 54

Expanding the brackets:
50 + 10x + 20x + 4x^{2} - 50 = 54
4x^{2} + 30x = 54
2x^{2} + 15x - 27 = 0
2x^{2} - 3x + 18x - 27 = 0
x(2x - 3) + 9(2x - 3) = 0

(x + 9)(2x - 3) = 0
x = -9, or x = 3/2

Since x > 0, then x ≠ -9
Thus, the only x-value we can take is x = 3/2
