Help me answer all of them even the word problem

Answer and Explanation:

When you raise a power to a power, you multiply the two exponents. As you can see, .

1. . So, the answer is k^20

2. . So, the answer is 8^14

3. When you have two items that you're taking the power of, you put the exponent on both terms. For example, here:

. So, the answer is 64p^12

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
