I need to graduate please. Which expression is a perfect cube? x^8 y^24 m^26 s^64

myrzilka [38]

Remember
$(a^b)^c=a^{bc}$

note that if $a^3$ is a perfect cube then $(a^3)^c$ is also a perfect cube when c is an integer

$(a^3)^c=a^{3c}$
so if a number is a perfect cube then the power must be divisible by 3

8 is not divisible by 3
24 is divisible by 3
26 is not divisibley by 3
64 is not divisible by 3

the perfect cube is y^24

Xelga [282]

Hello there!

35/100 watch more then 10 hours a week

3000 is 30 times greater than 100 so we can simply multiply 35/100 by 30.

35/100 x 30 = 1050/3000

Therefore, if the company had 3,000 subscribers, 1,050 subscribers would be watching more than 10 hours a week.
