Y²(3⁴)×7⁸ I don't understand this, can someone explain to me please?

In order to multiply two exponential expressions together, they must have the same base, and all you need to do is add the exponents. This works if the exponents are positive or negative, but only if the bases are the same. If the terms have different bases, there is not much that can be done to simplify.

Step-by-step explanation:

it isn't the answer but i hope it helps you :)

so basically, y is a number, and you see those little numbers above the bigger number. Yeah, well you have to times that number by itself.

Example: 3⁴ = 3 x 3 x 3 x 3 = 81

Hope this helps

Step-by-step explanation:

yes

step-by-step explanation:

yes

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
