Despite the other answer, this looks like exponentiation.

The parentheses are necessary; without them

$4^{3^5}=4^{(3^5)}$

which happens to be 147 digits long.

We're asked

$(4^3)^5$

Parenthesized this way we can multiply the exponents

$(4^3)^5 = 4^{15}=(2^2)^{15}=2^{30}$

Two to the thirtieth is 1,073,741,824, about a billion. But that's not really that helpful for understanding what's going on so let's leave it as a power of two.

Answer: $2^{30}$

Oceanside Bike Rental Shop charges 13 dollars plus 9 dollars an

enyata [817]

In this question, we're trying to find how many hours Mike had the bike for.

We know that 13 dollars as a flat rate.

We also know that they charge 13 dollars and hour.

Mike paid a total of 67 dollars for the bike.

Lets represent this as an equation:

67 = 9x + 13

x = hours the bike was rented

Solve for x:

67 = 9x + 13

Subtract 13 from both sides

54 = 9x

Divide both sides by 9

6 = x

This means that Mike rented the bike for 6 hours.

Answer:

6 hours

Dakota wants to build 8 birdhouses, he needs to point 6 square feet of plywood, for each birdhouse is the plywood cause $0.56 pe

Westkost [7]

Answer:

$26.88

Step-by-step explanation:

Cost of a ply wood = $0.56 per square foot

If Dakota wants to build 8 birdhouses and he needs to paint 6 square feet of plywood for each birdhouse, then the total area fir the 8 bird house will be expressed as:

8 * 6

= 48 sq. feet

Hence the area of 8 bird houses is 46sq. feet

Next is to calculate the amount it will cost to make the 8 bird houses.

Since 1 sq. foot = $0.56

48 sq. feet = y

cross multiply

y * 1 = 48 * 0.56

y = 26.88

Hence it will cost Dakota $26.88 to make hid bird houses

Find the value of tan(sin^-1(1/2))

suter [353]

If you know that $\sin\dfrac\pi3=\dfrac12$ , then you know right away

$\tan\left(\sin^{-1}\dfrac12\right)=\tan\dfrac\pi3=\dfrac1{\sqrt}3=\dfrac{\sqrt3}3$

###

Otherwise, you can derive the same result. Let $\theta=\sin^{-1}\dfrac12$ , so that $\sin\theta=\dfrac12$ . $\sin^{-1}$ is bounded, so we know $-\dfrac\pi2\le\theta\le\dfrac\pi2$ . For these values of $\theta$ , we always have $\cos\theta\ge0$ .
