In which expression should the exponents be multiplied?

you should use P.E.D.A.S

Step-by-step explanation:

Parentheses,

Exponents,

Multiplication

Division (from left to right),

Addition

Subtraction (from left to right).

If we have the same base, we can do this: (1/3)^4*(1/3)*7 = (1/3)^(4+7) = (1/3)^11 3^7/3^15 = (3^7)*(3*(-15)) = 3^(7 + (-15)) = 3^(-8) = 1/(3^8) 4^5*4^2 = 4^(5+2) = 4^7

but i think you're anserw would be 135

Step-by-step explanation:

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
