Evaluate \[\sqrt{64} + 5^2 - 11 - \sqrt{9}\]

OpenStudy (tylerd):

is the 5^2 inside the square root?

OpenStudy (tylerd):

square root of 64 = 8, 5^2 = 25, square root of 9 = 3

OpenStudy (tylerd):

then you just add/subtract

OpenStudy (tylerd):

ok 8+25-11+3 = ? enter that in your calculator

OpenStudy (tylerd):

25

OpenStudy (just_one_last_goodbye):

25?

OpenStudy (tylerd):

if we have \[\sqrt{64} =\sqrt{32x2}=\sqrt{16x2x2}=\sqrt{8x2x2x2}=\sqrt{4x2x2x2x2}=\sqrt{2x2x2x2x2x2}\]
