Aldo made an international phone call for 4.5 minutes. he was charged $0.26 for each minute. find the amount he paid.

Multiply .26 by 4.5

.26*4.5= 1.17 

He paid $1.17 for the international call.

I hope this helped!

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
