what is the step to this problem (5^4)^1/2

Because the equation is taking a power to a power, you can use the power rule, which states that a^m^n is the same as a^(m*n)

5^(4*1/2)=5^2=25

DarkBlaze you have made a careless error      Can you fix it please.   

Taken care of.

k, 5 to the 4th power, this means:

5*5*5*5

5*5=25*5=125*5=625

overall, 5^2 is equal to 625.

HOWEVER, then we have ^1/2

so, 625^1/2, and that equals:

312.5

overall, the correct answer is:

312.5

or as Titanium Rome would say, just for God's sake, 312.5 number thingys

ITS 312.5 NUMbER THINGYS!!!!

once again, my friend, you've done well

Thanks DarkBlaze347      

Heather, you got in a real mess   LOL
