Searches related to Anita needs 5 pounds of bananas to make banana bread for a bake sale. Each pond of bananas cost 0.50. How can Anita use place-value blocks to find the total cost of the bananas? What is the total cost?

$2.5

Step-by-step explanation:

Number of pounds of banana needed = 5 pounds

Cost per pound of banana = 0.50

To solve using place value blocks :

Ignoring the decimal in the cost per pound:

We can first take the product of 5 (Number of pounds of banana) and take cost per pound as 5. Since it is easier to make direct multiplication without decimal.

5 * 5 = $25

Now we can add the one decimal point (in the cost per pound) to our result

Then we have $2.5

Hence, total cost = $2.5

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
