Using the property of exponents, what do you need to multiply 10^2 by to get 10^4 ?

We conclude that using the property of exponents, we need to multiply 10² to get 10⁴.

Step-by-step explanation:

Let 'x' be the number we need to multiply 10² by to get 10⁴.

So the expression becomes

Divide both sides by 10²

Apply the exponent rule:

so the expression becomes

Therefore, we conclude that using the property of exponents, we need to multiply 10² to get 10⁴.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

i do not know this sorry : (
