What expression is equivalent to y•y•y•z•z•z•z

y^3 * z^4

Step-by-step explanation:

y*y*y = y^3

z*z*z*z = z^4

y³z⁴

Step-by-step explanation:

There's 3 y's and 4 z's. An exponent is the number of times which you multiply something by itself. In this case, you're multiplying y three times and z four times.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
